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

(−2, −2)(−2, −2) , (4, −2)(4, −2) , (5, 1)(5, 1) , (2, 3)(2, 3) , (−1, 1)

Enter your answer in the box.

___ units²

Sorry for the easy question, I'm just dumb

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

This is someting that might help you!
