Question

The breadth and length of a rectangle are in ratio 2:3 it's perimeter is30 cm find the length and breadth​

Answer 1

let the length and breadth be 3x and 2x respectively

perimeter of rectangle = 2( L× B)

30 = 2( 2x × 3x)

30/2 = 6x

15 = 6x

15/6 = x

x = 5/3

put x = 5/3 in breadth and length

3x = 3× 5/3

= 5

2x = 2 ×5/3

= 10/3
