Mike wants to fence in part of his backyard. He wants the length of the fenced-in area to be at least 20 feet long, l ≥ 20. He has 200 feet of fencing. The inequality that models the possible perimeter of the yard is 2l + 2w ≤ 200.
Which are possible dimensions for Mike’s backyard? Check all that apply.

Answer 1

W = 10 ft; l = 50 ft is Correct

w = 90 ft; l = 30 ft is Correct
