Problem Solving (PS) | Re: In the figure above, the area of the square EFGH is what percent of

Taken that ABCD is square, relationship of inner sides of triangle AGD is 2^1/2 / 1 / 1

Area ABCD = (2^1/2)^2 = 2
Area AGD = 1/2 * 1 * 1 = 1/2
Area FGHE = 1/2*1/2 = 1/4 (taken that side of squre FGHE is equal to half of side of triangle AGD)

Area FGHE / Area ABCD = 1/4 / 2 = 1/8 or 12,5%

Answer B
