the middle is a square which measures 20. to find its area, l•w, so 20•20.
to find area or a triangle, you would need the base and the height. the height is 9, and the base is 20 bc of the sides of the squares. the area for the triangle would be 90. multiple this by 4.
after adding 400 + 360 = 760. 760 should be your answer. sorry if i'm wrong.
