Question

The length and breadth of a rectangle are in the ratio 8 : 5. The length is 9 centimetres more than the breadth. What are the length and breadth of the rectangle?

Answer 1

Let the length of the rectangle = 8x and breadth = 5x

Their difference = 8x – 5x = 3x

This is given as 9 m, 8x – 5x = 9

3x = 9, x = 9 ÷ 3 = 3

∴ Length of the rectangle = 8 × 3 = 24 cm

Breadth of the rectangle = 5 × 3 = 15 cm
