Solve the problem.A cattle pen is constructed with solid wood walls. The pen is divided into four rectangular compartments. Each compartment is x feet long and y feet wide. The walls are x - 8 feet high.
Find the total surface area of the walls used in the cattle pen. Express the answer in factored form.
A. Surface area = (x - 8)2(5x + 8y) ft2
B. Surface area = (x - 8)(x + y) ft2
C. Surface area = (x - 8)(2x + 8y) ft2
D. Surface area = (x - 8)(5x + 8y) ft2
