Thus, the area of the remaining part of the land = Area of land - area of the flower bed
= 20 m^2 - 5 m^2 = 15 m^2


Question:1 0 By splitting the following figures into rectangles, find their areas (The measures are given in centimetres).

1643093070976

Answer: (a) Split the given figures into small rectangular parts as shown here;
2653
Now, the area of the rectangle (I) = l\times b = 4 \times 3 = 12 cm^2
the area of the rectangle (II) = l\times b = 3 \times 2= 6 cm^2
the area of the rectangle (III) = l\times b = 4 \times 1 = 4 cm^2
the area of the rectangle (IV) = l\times b = 3 \times 2 = 6 cm^2

So, the total area of the figure = sum area of all rectangles
= (12 + 6 + 4 + 6) cm^2
= 28 cm^2

(b) Split the given figure into smalle rectangles as shown here;
3654
the area of the rectangle (I) = l\times b = 3 \times 1 = 3 cm^2
the area of the rectangle (II) = l\times b = 3 \times 1= 3 cm^2
the area of the rectangle (III) = l\times b = 3 \times 1 = 3 cm^2 ?

Therefore, the total area of the figure = sum of the area of all the small rectangles
= 3+3+3
= 9cm^2

Question:11 Split the following shapes into rectangles and find their areas. (The measures are given in centimetres)

1643093104177

Answer: (a) Split the given figure into a small rectangle, as shown here;

Now, the area of the rectangle (I) = l\times b = 12 \times 2 = 24cm^2
the area of the rectangle (II) = l\times b = 8 \times 2= 16cm^2

Therefore, Total area = 24cm^2 + 16cm^2 = 40cm^2

(b) Split the given figure into a small rectangle, as shown here;
23654

Now, the area of the rectangle (I) = l\times b = 7 \times 7 = 49 cm^2
the area of the rectangle (II) = l\times b = 21 \times 7= 147 cm^2
Now, the area of the rectangle (III) = l\times b = 7 \times 7 = 49 cm^2

Therefore, Total area = 49cm^2 + 147cm^2 + 49cm^2 = 245 cm^2

(c) Split the given figure into a small rectangle, as shown here;

1643093132100

Now, the area of the rectangle (I) = l\times b = 2 \times 1 = 2 cm^2
the area of the rectangle (II) = l\times b = 5 \times 1= 5 cm^2
Now, the area of the rectangle (III) = l\times b = 2 \times 1 = 2 cm^2

Therefore, Total area = 2 cm^2 + 5cm^2 + 2cm^2 = 9cm^2

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.

Answer: Given that,
the length and breadth of the tiles are 12 cm and 5 cm

Therefore, the area of the tiles
= length \times breadth
= 12 cm \times 5 cm
= 60 cm 2

Now, (a) For 100 cm and 144 cm rectangular region,
Area of region = length \times breadth
= 14,400 cm 2

Therefore, the number of tiles needed = \frac{14,400}{60}=240 tiles

(b) For 70 cm and 36 cm rectangular region,
Area of region = length \times breadth
= 70 cm \times 36 cm
= 2520 m 2

Required number of tiles = \frac{2520}{60}=42
