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.
Answer:
4 : 18, 8 : 36
Step-by-step explanation:

2 x 2 = 4
9 x 2 = 18
4 x 2 = 8
18 x 2 = 36
We get 4 : 18, 8 : 36.
