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.

Answer 1

Answer: 398

Step-by-step explanation: First I find the area of the biggest triangle 20x20x1/2=200.

Then I find the area of the rectangle by cutting off the triangle at the end 6x30=180.

After that I find the area of the small triangle 6x6x1/2=18.

Finally, I add all the area up and 18+180+200= 398

Hope this helps :)

Answer 2

Answer:

398

Step-by-step explanation:

To find the answer all you have to do is to find the area of this shape. Area= Base x Height.

First step: Is to subtract 26-6. That will give you 20. 

Second Step:  That will give you 200 because 20 × 20= 400 / 2 = 200.

Third Step: Calculate the triangles by cutting them. . That will give you 18 because 6 × 6= 36, and 36 / 2 = 18.

Fourth Step: Multiply 30x6. 30x6=180

Final Step:Add 200+180+18. That will give you 398. 

Lisa has to cut 398 square feet of her grass.
