Question

What is the area of the composite figure whose vertices have the following coordinates?

(−8, 3) , (−4, 4) , (−1, 1) , (−4, −2) , (−8, −2)

Answer 1

well, on the left you have a four sided figure with parallel vertical left and right sides. The height on the left is 5 and on the right it is 6 so the average height is 5.5 and the base is 4 so that left partt has area = 4 * 5.5 = 22
then on the right you have an isoseles triangle with vertical base = 6 and altitude = -1 - -4 = 3 so area = 18
18+22 = 40

Answer 2

thank you very much sir
