Fields X and Y are to be enclosed with fencing that costs $ 24 per meter.

Column A                                              Column B
The cost of the fencing needed to enclose X           The cost of the fencing needed to enclose Y
选项 A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given
答案 C
解析 本题的正确答案为(C)。此题也就是求两场地的周长孰大孰小。但该题并不必要把两块场地的周长的值算出来。如下图所示把X场地补上虚线：  从图中可以看出X与Y周长相等，自然围墙所用的成本也相等。
