Length: 20
Width: 12
Width: 12
Width = W feet.
Length = W+8 Ft.
Width = W+4.
Length = W+3.
A1 = A2, (W+8)*W = (W+3)*(W+4),
W^2 + 8W = W^2 + 4W + 3W + 12,
W = 12 Ft., W+8 = 20 Ft.
Length = W+8 Ft.
Width = W+4.
Length = W+3.
A1 = A2, (W+8)*W = (W+3)*(W+4),
W^2 + 8W = W^2 + 4W + 3W + 12,
W = 12 Ft., W+8 = 20 Ft.
