Need help with finding Area.

12 square feet

Step-by-step explanation:

First we will find what we know, the square on the left side.

2 x 2 = 4.

Now, we have the triangle right.

10 - 2 = 8 for the length. Our sides are 8.2, 2, and 8. We just need the length and width.

2 x 8 = 16

16 / 2 = 8 (since it is a triangle)

Adding the together results in our answer which is,

4 + 8 = 12 square feet

(if I a wrong I am so sorry, good luck and have a nice day!)

the answer is d. 75%
