Find the area of the trapezoid.

103.5

Step-by-step explanation:

The area for the trapezoid is Area = ((a+b)/2)h where a = base 1, b = base 2, and h = height. 15 + 8= 23, and divided by 2 is 11.5. 11.5 x 9 = 103.5. Hope it helps.

The answer is 24.

First, we need to get -15 to 15.

-15 + 15 = 0.

Now we need to get 9.

0 + 9 = 9

Now add 9 with the 15 we added first.

15 + 9 = 24.
