Lisa has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. calculate the area of the polygon. be sure to show all your work and explain your answer.

I'm going to split this shape into 3, 2 triangles and a rectangle. To find the area of the rectangle, you would do 30 × 6 = 180ft. The triangle on the left would be 20 (26 - 6) × 20/2, so 400/2 = 200ft. The bottom triangle would be 6 × 6 (36 - 30)/2 = 36/2 = 18ft. When you add them all up (180 + 18 + 200) you get 398ft as your answer. I hope this helps!
