The perimeter of a 7-sided figure is 15. If the length of each side of the figure is increased by 2 units, what is the perimeter of the new figure?
A. 17
B. 22
C. 24
D. 29
E. 30
|
正确答案: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. |
