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 the correct answer:
A) 8√2	B) 9√3	C) 18	D) 16√2	E) 24
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 )= 
<gadget id="calculator">8*8 - (1/2 * 4 * 4 + 1/2 * 4 * 8 + 1/2 * 4 * 8 )</gadget>
