Question

Find the area of each figure given above by using the formula.
Find the area of each rectangle with the following measuremer
(al Length = 9 cm (b) Length = 4.5 m
Breadth = 7 cm
Breadth = 3 m
c) Length = 12.8 m (d) Length = 2.2 km
Breadth = 9 m
Breadth = 2 km​

Answer 1

Answer:

1 ) 63

2) 13.5

3) 115.2

4) 4.4

Answer 2

We need to recall the following formula for the area of a rectangle.

• Area of a rectangle $=Length\times Breadth$

This problem is about the area of a rectangle.

Given:

(a) Length $=9$ cm, Breadth $=7$ cm

The area of a rectangle is,

$Area=9\space\ cm\times 7\space\ cm$

$Area=63\space\ cm^2$

(b) Length $=4.5$ m, Breadth $=3$ cm

The area of a rectangle is,

$Area=4.5\space\ m\times 3\space\ m$

$Area=13.5\space\ m^2$

(c) Length $=12.8$ m, Breadth $=9$ m

The area of a rectangle is,

$Area=12.8\space\ m\times 9\space\ m$

$Area=115.2\space\ m^2$

(d) Length $=2.2$ km, Breadth $=2$ km

The area of a rectangle is,

$Area=2.2\space\ km\times 2\space\ km$

$Area=4.4\space\ km^2$
