Question

the perimeter of a rectangle is 20m. If the length and breadth are 2:3find them?

Answer 1

Let The length and breadth of the rectangle be 2x and 3x respectively.
Perimeter=2(l+b)=20 m
2(2x+3x)=20
=2*5x=20
=10x=20
=x=20/10
=x=2
Length=4 m
Breadth=6 m

Answer 2

let length is 2x and breadth is 3x
then,
2(l+b)=20
2(2x+3x) = 20
10x = 20
x = 2
so
length = 4m and breadth = 6m
