A) The area of the rectangle ABCD is base times height. 20in x 12in = 240 in sq. B) The area of the triangle AED is base times height divided by two. (14in x 12in)/2 = 84in sq. C) Figure EBCD is a right trapezoid (having one pair of parallel sides, while the others are slanted and forming a right angle). D) Area of EBCD is the area of the rectangle minus the area of the triangle. 240in sq - 84in sq = 156in sq.
