Question

The length of a rectangle is 5 times the width. If the perimeter is to be greater than or equal to 108 meters. What are the possible values of the width?

Answer 1

length = 5(width)
perimeter is 2l + 2w
The perimeter must be ≥ 108 meters
5w + 5w + w + w ≥ 108
12w ≥108
divide both sides by 12
w ≥ 9

The width can be greater than or equal to 9 meters.

Hope this helps
