Question

A rectangle has an area of 12cm2.
If each side has its length doubled

Answer 1

Answer:

Step-by-step explanation:

Area of rectangle = l x b

12cm2 = 4 x 3

length = 4

breadth = 3

Making length triple. = 2( 4x3) = 2 x 12 = 24

So new length = 24

breadth = 3

So the new area is 24 x 3 = 72cm2.

Answer 2

L=4 cm

B=3 cm
So area os 4x3= 12 cm
