okay, you're going to want to separate this into a large rectangle and a triangle.
From there you're going to calculate the area of both.
rectangle formula:
A= L*H
Triangle Formula:
A= (L*H)/2
Then you just plug in the numbers and calculate, getting 18 for the rectangle and 16 for the triangle. 18+16 = 34
You add the two areas together as shown above, and then you have your area for the whole shape!
