In the figure, each side of square ABCD has length 1, the length of line segment CE is 1, and the length of line segment BE is equal to the length of line segment DE. What is the area of the triangular region BCE?
A.1/3
B.(√2)/4
C.1/2
D.(√2)/2
E.3/4
答案為B。
這題室GWD二號題組,但是似乎有兩套二號。我看板大把這套題歸在(GMAT2)裡。
我的問題是,由於BC=1 且 CE=1 即可得知三角形BCE的高為√2, 則答案不就是D?
嗚嗚! 不懂為什麼會變成B,麻煩大家指正! 謝謝
