题目明白对OG中解释一个问题不太明白
2.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.

DS 题 OG 说 Determine whether the length and width of the sheet of glass are greater than or equal to the length and width of the tabletop.
但是题意中不是说了it covers the entire tabletop and its edges are parallel to the edges of the tabletop. 都说了parallel to the edges of the tabletop 为啥解释时说 greater than ? 那不就都超出了不符合题目需要的条件了么?
先谢谢来回答的NN们！

it covers the entire tabletop and its edges are parallel to the edges of the tabletop. 這是題的要求吧, 不是已知...

還有,less than也可以是parallel... 不知道這樣有沒有回答到你的問題

谢谢昂！！！
那就是说只要length 和 width 大于桌面就成立了是么
