Question 4.
Rani had Rs. 18.50. She bought one ice-cream for Rs. 11.75. How much money does she have now?
Solution:
Total money = Rs. 18.50
Cost of ice-cream = Rs. 11.75
Amount left = Rs. 18.50 – Rs. 11.75 = Rs. 6.75
Therefore, Rani has Rs. 6.75 now.

Question 5.
Tina had 20 m 5 cm long cloth. She cuts 4 m 50 cm length of cloth from this for making a curtain. How much cloth is left with her?
Solution:
Total length of cloth = 20 m 5 cm = 20.05 m
Length of cloth used = 4 m 50 cm = 4.50 m
Remaining cloth = 20.05 m – 4.50 m = 15.55 m
Therefore, 15.55 m of cloth is left with Tina.

Question 6.
Namita travels 20 km 50 m every day. Out of this she travels 10 km 200 m by bus and the rest by auto. How much distance does she travel by auto?
Solution:
Total distance travelled = 20 km 50 m = 20.050 km
Distance travelled by bus = 10 km 200 m = 10.200 km
Distance travelled by auto = (20.050 – 10.200) km = 9.850 km
Therefore, 9.850 km distance is travelled by auto.

Question 7.
Aakash bought vegetables weighing 10 kg. Out of this, 3 kg 500 g is onions, 2 kg 75 g is tomatoes and the rest is potatoes. What is the weight of the potatoes?
Solution:
Weight of onions = 3 kg 500 g = 3.500 kg
Weight of tomatoes = 2 kg 75 g = 2.075 kg
Total weight of onions and tomatoes
= (3.500 + 2.075) kg = 5.575 kg
Therefore, weight of potatoes
= (10.000 – 5.575) kg = 4.425 kg
Thus, weight of potatoes is 4.425 kg.

व्याख्या-डॉ. होमी जहाँगीर भाभा अणु’ की शक्ति को पहचानते थे। साथ ही, वह यह भी जानते थे कि ‘अणुबम’ के रूप में इसकी ताकत का गलत उपयोग, मानव सभ्यता के लिए काफी खतरनाक होता है। अणुबम के विध्वंस से पलभर में हजारों-लाखों जिन्दगियाँ काल के गाल में समा जाती हैं। अत: वे अणु-शक्ति का सही उपयोग करके इस विलक्षण ‘ऊर्जा’ को मानव की सेवा में तथा शांतिपूर्ण एवं रचनात्मक कार्यों में लगाना चाहते थे।

(2) उनकी कलात्मक रुचि का परिणाम है कि दाम्बे के अणु-शक्ति संस्थान में बगीचे तथा पौधों की सजावट सौन्दर्यपूर्ण एवं कलापूर्ण दिखाई देती है। टाटा इंस्टीट्यूट की गैलरियों तथा कमरों में सजे चित्र एवं वहाँ के उपवन उनकी वैज्ञानिकता एवं कलात्मकता के सुन्दर संगम हैं।

संदर्भ-पूर्व की तरह।

प्रसंग-प्रस्तुत पंक्तियों में डॉ. भाभा की कलात्मकता एवं रुचियों का वर्णन किया है।

व्याख्या-डॉ. भाभा के अन्दर कला के प्रति रुझान था जिसका नतीजा यह है कि उन्होंने अणुशक्ति केन्द्र ट्राम्बे में एक बगीचा विकसित किया है। इस बगीचे कों अनेक पेड़-पौधों से सुन्दर बनाया है, उसकी सजावट में इन्हीं पौधों को विशेष महत्व है। यह सजावट अति कलापूर्ण है। टाटा इन्स्टीट्यट की गैलरियों और अन्य कमरों की सजावट भी चित्रों द्वारा की गई है। ये चित्र भी डॉ. भाभा की कलात्मक रुचि को प्रकट करते हैं। वहाँ के बगीचे और समीप वाले उपवनों के विकास में वैज्ञानिकता झलकती है और उनकी कला का अनोखा जोड़ है, मिश्रण है। इस तरह डॉ. भाभा की वैज्ञानिकता में उनकी कलात्मकता का योग बेजोड़

(3) भारत के इस महान सपूत की स्मृति में ट्रॉम्बे के अणु-शक्ति केन्द्र का नाम बदलकर ‘भाभा अणु-शक्ति अनुसन्धान केन्द्र’ कर दिया गया। डॉ. भाभा आज भले ही हमारे बीच न हों परन्तु उन्होंने विज्ञान जगत को जो अमूल्य योगदान दिया है उससे भावी वैज्ञानिकों को सदा मार्गदर्शन मिलता रहेगा।

सन्दर्भ-पूर्व की तरह।

प्रसंग-डॉ. भाभा के द्वारा विज्ञान जगत के लिए किए गए कार्यों का महत्व बताया गया है।

व्याख्या-डॉ. भाभा भारत के बहुत बड़े महत्वपूर्ण पुत्र थे। वे आज इस दुनिया में हमारे बीच नहीं हैं, परन्तु विज्ञान के संसार में उन्होंने जो भी हमारे लिए किया है, उसका महत्व महान है। विज्ञान जगत में किया गया उनका कार्य बेजोड़ है। उनकी यादगार के लिए ही ट्रॉम्बे के अणुशक्ति केन्द्र का नाम बदल दिया है और उसका नाम ‘भाभा अणु-शक्ति अनुसन्धान केन्द, कर दिया गया है। उनके वैज्ञानिक प्रयोगों और खोजों से भविष्य के वैज्ञानिकों को उस क्षेत्र में आगे बढ़ने के लिए दिशा-निर्देशन मिलेगा और मानवता की भलाई होती रहेगी। संसार में सुख-समृद्धि होती रहेगी।

Find the areas of the rectangles whose sides are:
(a) 3 cm and 4 cm
(b) 12 m and 21m
(c) 2 km and 3 km
(d) 2 m and 70 cm
Solution:
(a) Area of rectangle = length × breadth
= 3 cm × 4 cm = 12 cm2

(b) Area of rectangle = length × breadth
= 12 m × 21 m = 252 m2

(c) Area of rectangle = length × breadth
= 2 km × 3 km = 6 km2

(d) Area of rectangle = length × breadth
= 2 m × 70 cm = 2 m × 0.7 m = 1.4 m2

Question 2.
Find the areas of the squares whose sides are:
(a) 10 cm
(b) 14 cm
(c) 5 m
Solution:
(a) Area of square = side × side
= 10 cm × 10 cm = 100 cm2

(b) Area of square = side × side
= 14 cm × 14 cm = 196 cm2

(c) Area of square = side × side
= 5 m × 5 m = 25 m2

Question 3.
The length and breadth of three rectangles are as given below:
(a) 9 m and 6 m
(b) 17 m and 3 m
(c) 4 m and 14 m
Which one has the largest area and which one has the smallest?
Solution:
(a) Area of rectangle = length × breadth
= 9m × 6m = 54m2

(b) Area of rectangle = length × breadth
= 17 m × 3 m = 51 m2

(c) Area of rectangle = length × breadth
= 4 m × 14 m = 56 m2
Thus, rectangle (c) has the largest area, i.e. 56 m2 and rectangle (b) has the smallest area, i.e., 51 m2.

Question 4.
The area of a rectangular garden 50 m long is 300 sq m. Find the width of the garden.
SolutionL
Length of rectangle = 50 m
Area of rectangle = 300 m2
Since, area of rectangle = length × breadth
Therefore, breadth = \(\frac{\text { area of rectangle }}{\text { length }}\)
= \(\frac{300}{50}\) m = 6 m
Thus, the breadth of the garden is 6 m.

Question 5.
What is the cost of tiling a rectangular plot of land 500 m long and 200 m wide at the rate of Rs. 8 per hundred sq m?
Solution:
Length of land = 500 m
Breadth of land = 200 m
Area of land = length × breadth
= 500 m × 200 m = 1,00,000 sq m
Cost of tiling 100 sq m of land = Rs. 8
∴ Cost of tiling 1,00,000 sq m of land
= Rs. \(\frac{8 \times 100000}{100}\) = Rs. 8000

Question 6.
A table-top measures 2 m by 1 m 50 cm. What is its area in square metres?
Solution:
Length of table-top = 2 m
Breadth of table-top = 1 m 50 cm = 1.50 m
∴ Area of table-top = length × breadth
= 2 m × 1.50 m = 3 m2

Question 7.
A room is 4 m long and 3 m 50 cm wide. How many square metres of carpet is needed to cover the floor of the room?
Solution:
Length of room = 4 m
And breadth of room = 3 m 50 cm = 3.50 m
∴ Area of carpet = length × breadth
= 4 m × 3.50 m = 14 m2

Question 8.
A floor is 5 m long and 4 m wide. A square carpet of sides 3 m is laid on the floor. Find the area of the floor that is not carpeted.
Solution:
Length of floor = 5 m
And breadth of floor = 4 m
Area of floor = length × breadth
= 5m × 4m = 20m2
Now, side of square carpet = 3 m
Area of square carpet = side × side
= 3m × 3m = 9m2
∴ Area of floor that is not carpeted
= 20 m2 – 9 m2 = 11 m2

Question 9.
Five square flower beds each of sides 1 m are dug on a piece of land 5 m long and 4 m wide. What is the area of the remaining part of the land?
Solution:
Side of square flower bed = 1 m Area of square flower bed = side × side
= 1m × 1m = 1m2
∴ Area of 5 square flower beds = (1 × 5) m2
= 5 m2
Now, length of land = 5 m
And breadth of land = 4 m
∴ Area of land = length × breadth = 5m × 4m
= 20 m2
∴ Area of remaining part
= Area of land – Area of 5 flower beds
= 20 m2 – 5 m2 = 15 m2

Area of square HKLM = 3 × 3 cm2 = 9 cm2
Area of rectangle I]CH = 1 × 2 cm2 = 2 cm2
Area of square FEDG = 3 × 3 cm2 = 9 cm2
Area of rectangle ABCD = 2 × 4 cm2 = 8 cm2
∴ Total area of the figure = (9 + 2 + 9 + 8) cm2 = 28 cm2

(b) We have,
MP Board Class 6th Maths Solutions Chapter 10 Mensuration Ex 10.3 3
Area of rectangle ABCD = 3 × 1 cm2 = 3 cm2
Area of rectangle BJEF = 3 × 1 cm2 = 3 cm2
Area of rectangle FGHI = 3 × 1 cm2 = 3 cm2
∴ Total area of the figure = (3 + 3 + 3) cm2 = 9 cm2

Question 11.
Split the following shapes into rectangles and find their areas. (The measures are given in centimetres).
MP Board Class 6th Maths Solutions Chapter 10 Mensuration Ex 10.3 4
Solution:
(a) We have,
MP Board Class 6th Maths Solutions Chapter 10 Mensuration Ex 10.3 5
Area of rectangle ABCD = 2 × 10 cm2 = 20 cm2
Area of rectangle DEFG = 10 × 2 cm2 = 20 cm2
∴ Total area of the figure = (20 + 20) cm2
= 40 cm2

(b) We have,
MP Board Class 6th Maths Solutions Chapter 10 Mensuration Ex 10.3 6
There are 5 squares each of side 7 cm.
Area of one square = 7 × 7 cm2 = 49 cm2
∴ Area of 5 squares = 5 × 49 cm2 = 245 cm2

(c) We have,
MP Board Class 6th Maths Solutions Chapter 10 Mensuration Ex 10.3 7
Area of rectangle ABCD = 5 × 1 cm2 = 5 cm2
Area of rectangle EFGH = 4 × 1 cm2 = 4 cm2
∴ Total area of the figure = (5 + 4) cm2
= 9 cm2

Question 12.
How many tiles whose length and breadth are 12 cm and 5 cm respectively will be needed to fit in a rectangular region whose length and breadth are respectively:
(a) 100 cm and 144 cm
(b) 70 cm and 36 cm.
Solution:
(a) Area of rectangular region
= length × breadth = 100 cm × 144 cm = 14400 cm2
Area of one tile = 12 cm × 5 cm = 60 cm2
MP Board Class 6th Maths Solutions Chapter 10 Mensuration Ex 10.3 8
Thus, 240 tiles are required.

(b) Area of rectangular region
= length × breadth = 70 cm × 36 cm = 2520 cm2
Area of one tile = 12 cm × 5 cm = 60 cm2
∴ Number of tiles
= \(\frac{\text { Area of rectangular region }}{\text { Area of one tile }}=\frac{2520}{60}\) = 40
Thus, 42 tiles are required.
