Answer:
51
Explanation:
You can split the polygon into two shapes, a triangle and a square. First, let's find the area of the square. The length of this figure is 7 and the height is 6. So, all we do is multiply 7 times 6 and get the area of the square to be 42.
Next, let's find the area of the triangle. The formula to find the area of a triangle is:
. The base (or length) of this figure is going to be 6, while the height of this figure is going to be 3. We can then plug in these numbers into the formula:
. This gives us the answer of 9.
We then can add these numbers up and get the area of the polygon to be 51 squared units.
