What is the perimeter, in meters, of a rectangular playground 24 meters wide that has the same area as a rectangular playground 64 meters long and 48 meters wide?
选项
A、112
B、152
C、224
D、256
E、304
答案
E
解析
The area of the rectangular playground that is 64 meters long and 48 meters wide is(64)(48)= 3,072 square meters. The second playground, which has the same area, is 24 meters wide and 3,072/24= 128 meters long. Therefore, the perimeter of the second playground is(2)(24)+(2)(128)= 304 meters. The correct answer is Choice E.
