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.

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.

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
