Question

A rectangle is 5 times as long as it is wide. If its perimeter is 288 metres, then find its length and breadth.​

Answer 1

Let be Breadth = X

Let be Length = 5X

Perimeter of rectangle = 2(L+B) = 2(5X+1X)

= 2×6X = 12X

Perimeter of rectangle = 288m

A/Q,

12X = 288

Or, X = 288 ÷ 12 = 24m

Breadth of rectangle = X = 24m (ans.)

Length of rectangle = 5X = 24×5 = 120m (ans.)

HOPE IT'S HELP YOU.
