coulomb \$m[1]:答案是B
之前好像有再版上看過

條件一
把線段LM長度設為t好了
那麼線段MN長度設為15-t
比不出來
條件二
他說三個小矩形一樣大
那就設小矩形的短邊長度為a
得出小矩形的長邊長度為2a（因為LM=2a=KN）
這樣就知道MN為3a
充分
ANS B

coulomb \$m[1]:可是他只有說三個小矩形的「面積」一樣
沒有說他們是完全相同的啊
也就是說他們的長寬比可能會不一樣
例如說 3x4=2x6=12 那這兩個面積一樣 可是一個長寬比是3:4 一個是2:6
還是說從哪一個條件可以看出這三個矩形的長寬比是一樣的呢？
謝謝 enim大大的回答∼∼
我想是出在於dimension這個字眼吧...
可以翻為“面積”也可以翻為“尺寸”
尺寸：長寬高
所以才會說他們全等
