Question

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.

Answer 1

Answer:

398 sq ft

Step-by-step explanation:

Because it does not matter how you place it (the area will always be the same!), you can just add up the areas: 20*20/2 + 6*6/2 + 30*6 = 200 + 18 + 180 = 398.
