Question

The length of a rectangle is 4 m mo
than its width. What are the dimensio
if the perimeter is 60 m?​

Answer 1

Answer:

length = 17m

width = 13m

Step-by-step explanation:

Let the width be x meters.

∴ the rectangle's length = (x + 4) meters

∴ perimeter = 2{(x + 4) + x}m = 2(2x + 4)m = (4x + 8)m

But it is given that perimeter = 60m

∴ 4x + 8 = 60

⇒ 4x = 60 - 8

⇒ x = 52/4 = 13

∴ width of rectangle = x meters = 13m

length of the rectangle = (x + 4)m = (13 + 4)m = 17m
