Question

A carpet has a perimeter of 320 feet. If the length is 3 times the width, what are the dimensions of the carpet?

The width = [a.) 120 b.) 40 c.) 80]
The length = [d.) 120 e.) 40 f.) 80]

Answer 1

Explanation:

p = 2×(l+w)

=> l = 3w

p = 2×(3w+w)

320 = 2× 4w

320 = 8w

=> w = 320/8 = 40

l = 3×40 = 120

so,

The width = b. ) 40 ft

The length = d.) 120 ft
