Width = W.
Length = 3W.
2W + 2L = 320.
2W + 2*3W = 320,
W = 40 Ft. = Width.
Length = 3W = 3*40 = 120 Ft.
Since the barn forms one end of the rectangle, we only need W + 2L:
W + 2L = 40 + 2*120 = 280 Ft.
Length = 3W.
2W + 2L = 320.
2W + 2*3W = 320,
W = 40 Ft. = Width.
Length = 3W = 3*40 = 120 Ft.
Since the barn forms one end of the rectangle, we only need W + 2L:
W + 2L = 40 + 2*120 = 280 Ft.
