Question 1013717: The dimensions of a rectangular piece of paper ABCD (shown in the diagram) are AB=10 and BC=9. It is folded so that the corner D is matched with a point F on edge BC.
EC = 4 (10-6=4)
FC = 5 (½ of 10 = 5)
EF = 6
EFC = 200 ((16 x 25)/2
Find a function for the area of triangle EFC in terms of x.
