F and E are midpoints of AB and AD respectively. If the side of square ABCD is 8, what is the area of triangle CEF?	Choose one
A) 8 √ 2 B) 9 √ 3 C) 18 D) 16 √ 2 E) 24

Rationale: area of shaded figure = area of square - ( area of triangle aef + area of triangle fbc + area of triangle edc ) = 8 * 8 - ( 1 / 2 * 4 * 4 + 1 / 2 * 4 * 8 + 1 / 2 * 4 * 8 ) = 24 . answer e .
Answer: E
