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
which length and width are possible dimensions for the garden?
l = 20 ft; w = 5 ft
l = 20 ft; w = 10 ft
l = 60 ft; w = 20 ft
l = 55 ft; w = 30 ft
