Question

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

Answer 1

Step-by-step explanation:

area of Rectangle = length X breadth

a) Length = 9 cm

Breadth = 7 cm

area= 9 X 7=63 sq cm

(c) Length = 12.8 m

Breadth = 9 m

area =12.8 X 9= 115.2 sq m

(b) Length = 4.5 m

Breadth = 3 m

area = 4.5 X 3 = 13.5 sq m

(d) Length = 2.2 km

Breadth = 2 km

area = 2.2 X 2 = 4.4 sq km

Answer 2

Answer:

a 63 cm

c 115.2cm

b 13.5

d 4.4

Step-by-step explanation:

area of rectangle = Length × breadth

= 9×7

= 63
