Mr. Smith is building a fence around his garden. The length is 3 feet longer than twice the width. The perimeter is 72 feet. Part A: Which equation could be used to determine w, the width, in feet of the sandbox? A. W + w + 3 = 72 B. W + 2w + 3 = 72 C. 2w + 2(w + 3) = 72 D. 2w + 2(2w + 3) = 72 Part B: What is the width, in feet, of the fencing required to surround the garden?
