Question

A rectangle has a length at least four more than five times the width. If the

perimeter is at least 44 units, find the least possible width.

Answer 1

width of 3 units

Explanation:

let 'w' = width

let '4+5w' = length

P = 2l + 2w

44 = 2(4+5w) + 2w

44 = 8 + 10w + 2w

36 = 12w

w = 36/12

w = 3
