Question

The length of a rectangle is three times its width.If the perimeter of the rectangle is 100metres,find the length and width of the rectangle.

Answer 1

Step-by-step explanation:

let the length of the rectangle be 3x

and the breadth of rectangle be x

A.T.Q

perimeter of rectangle = 2(l+b)

100= 2(3x+x)

100= 6x+ 2x

100= 8x

x= 100/8

x= 12.5m

now,

3x= 3x12.5 = 37.5m

x = 12.5m
