If the length of each side of the figure is increased by 2 units, what is the perimeter of the new figure? Answer Choices (A) 17 (B) 22 (C) 24 (D) 29 (E) 30 答案:D 解析:The perimeter is the sum of the lengths of all the sides. Since each of the seven sides is to be increased by 2, there will be a total increase of 14 in the perimeter. The original perimeter, 15, plus the increase, 14, gives the new perimeter, 29.
