Answer:
12 square feet
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!)
