Answer 1

203.67

Explanation:

all those numbers are confusing, but this is what i get from the picture

triangle area formula = 1/2 base * height

rectangle area formula = L * W

AB = 1/2 base * height, = 1/2 * 9 * 4, = 18

ab is the same as AB =18

C = 8.1 * 4.5 = 36.45

D = 8.1 * 7.2 = 58.32

E = 8.1 * 9 = 72.9

added together = 203.67
