Can a certain rectangular sheet of glass be positioned on a rectangular tabletop so that it covers the entire tabletop and its edges are parallel to the edges of the tabletop?

(1) The tabletop is 36 inches wide by 60 inches long.

(2) The area of one side of the sheet of glass is 2,400 square inches.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

Answer: e

为什么呀？

the sheet of glass 可以长为８０，宽为３０，那当然不能完全覆盖了

ＪＪ连续问了这么多个比较基本的问题，是不是还没有熟悉数学的套路啊？不过，多做几套ＧＷＤ，就ＯＫ了．
