There are a few ways to go about doing this problem. One method would to divide the shape into two triangles and a rectangle and then find the area of those shapes and then add them all up. I am not going to do that because that is the long way to solve this problem.
<u>With that said, you can use the trapezoid formula</u>
b1 = 3
b2 = 11
h = 9
<u>Plugin the data into our model and do the math.</u>
