Irina wants to build a fence around a rectangular vegetable garden so that it has a width of at least 10 feet. she can use a maximum of 150 feet of
fencing. the system of inequalities that models the possible lengths, l, and widths, w, of her garden is shown.

w ≥ 10

2l + 2w ≤ 150

a = 20 ft; w = 5 ft

b= 20 ft; w = 10 ft

c = 60 ft; w = 20 ft

d = 55 ft; w = 30 ft
