Question

The adjacent sides of a rectangle are in the ratio 2:3 and its perimeter is 80m long. Find the measure of sides

​

Answer 1

Let the common ratio be 'x'

breadth = 2x

length = 3x

perimeter = 80m

$2(l + b) = perimeter$

$2(2x + 3x) = 80$

$4x + 6x = 80$

$10x = 80$

$x = 8$

Therefore,

Lenght = 3 × 8

= 24m

Breadth = 2 × 8

= 16m
