吉纳维芙在她的大风筝上加支撑条，形式是连接风筝相对顶点的十字。她需要多少英寸支撑材料？
Genevieve puts bracing on her large kite in the form of a cross connecting opposite corners of the kite. How many inches of bracing material does she need?
答案：E
小提示：
支撑材料总长是两条对角线之和
The bracing is the sum of the two diagonals
大提示：
方格扩大三倍后，两条对角线长度也都扩大三倍
Tripling the grid triples both diagonal lengths
解答：
长对角线是 个单位，短对角线是 个单位。
在大风筝中，一个单位为 英寸，所以需要的支撑材料总长为
所以正确答案是 E。
The long diagonal is units, and the short one is units.
In the large kite, one unit is inches, so the total amount of bracing material needed is
Thus, E is the correct answer.
