Question

The sides of a rectangle are in the ratio 7:5 and its perimeter is 72cm.find the length and breadth of the rectangle?

Answer 1

Answer :

Let the sides of the rectangle in ratios be 7x and 5x

Perimeter = 2*(l+b)

72 = 2 * ( 7x + 5x )

72 = 2 * 12x

x = 72/24

x = 3

So the sides are ;

7x = 7 * 3 = 21 cm

5x = 5 * 3 = 15 cm
