The area of a storeroom with a rectangular floor is 2,800 square yards. The perimeter of the storeroom floor is 220 yards. Which system of equations will determine the length (l) and the width (w) of the storeroom floor?
A. Lw = 2,800 2l + w = 220
B. L + w = 220 l2 + w2 = 2,800
C. Lw = 220 2l + 2w = 2,800
D. Lw = 2,800 2l + 2w = 220
