Question

if the ratio of the length to the breadth of a rectangle B 5 ratio 3 and its perimeter is 144 M find the length of the rectangle

Answer 1

Let the length and breadth of the rectangle be 5x and 3x respectively.

Perimeter of the Rectangle = 144 m
2 ( l + b ) = 144
2 ( 5x + 3x ) = 144
2 ( 8x ) = 144
16x = 144
x = 144 / 16
x = 9


Length = 5x = 5 × 9 = 45 metres.
