Question

What is the area of the composes figure whese vertices have the following coordinates?(-2,-2),(3,-2),(5,-4),(1,-8),(-2,-4)

Enter your answer in the box

Answer 1

Area of a rectangle = W X L

Area of a rectangle = 5 X 2

Area of a rectangle = 10

Area of triangle 1= 1/2 X B X H

Area of triangle 1= 1/2 X 2 X 2

Area of triangle 1= 1/2 X 4

Area of triangle 1= 2

Area of triangle 2= 1/2 X B X H

Area of triangle 2= 1/2 X 7 X 4

Area of triangle 2= 1/2 X 28

Area of triangle 2= 14

Area of a rectangle + Area of triangle 1 + Area of triangle 2=

10 + 2 + 14 = 36
