The area of the ice surface of a skating rink is about 221 yd2. The rink is about the shape of a rectangle where the ice-surface width is 4 yd longer than its length. Find the dimensions of the surface. A. length = 13 yd, width = 17 yd B. length = 21 yd, width = 17 yd C. length = 17 yd, width = 21 yd D. length = 17 yd, width = 13 yd
