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. Six-sided polygon that includes two isosceles right triangles, one with height and base of 20 feet, the other height and base of 6 feet, and one rectangle measuring 30 feet by 6 feet.

First i decompose the shape into smaller shapes. Then I take the triangle and calculate it, 20 x 20 x1/2 which equals 200. Then i take the rectangle and calculate 6 x 30= 180. And the last shape, which is a triangle I calculate 6 x 6 x 1/2=18. I will add all the numbers together to get 398 ft.

Step-by-step explanation:

all but the second one

step-by-step explanation:

cuz that one goes over 180
