Solving real-world systems of inequalities

mike wants to fence in part of his backyard. he wants the which are possible dimensions for mike's backyard?

length of the fenced-in area to be at least 20 feet long, 72 check all that apply

20. he has 200 feet of fencing. the inequality that

models the possible perimeter of the yard is 21 + 2ws w = 50 ft: 2 = 10 ft

200

w = 10 ft 7 = 50 ft

w = 20 ft: 1 = 60 ft

w 790 ft; 7 = 30 ft

w = 50 ft 7 = 40 ft
