The dimensions of the rectangular pool shown below are 40 yards by 20yards. A fence will be built around the outside of the deck. The ratio of thedimensions of the fence to the dimensions of the pool is How many yardsof fence should be purchased to enclose the deck?A. 60 yardsB. 180 yardsC. 120 yardsD. 1200 yards
Accepted Solution
A:
You are looking for the perimeter of the pool. The perimeter of rectangles can be measured by using the formula 2W + 2L = P (2 * width + 2 * length = perimeter). Using the formula, 2(40) + 2(20) = P, 80 + 40 = P, P = 120. The answer is C. 120 yards.
