Find the area of this irregular polygon.

970m^{2}

Step-by-step explanation:

This polygon can be divided in two figures: one is a triangle, an the other one is a square.

We'll begin calculating the triangle's area, using the following formula:

Where:

As you can see, I added both sides of the triangle that measure 9 m and also the lenght of the square that measures 20 m! This added up is what the base of the triangle measures on total.

Now we are going to calculate the square's area, that is much more simple:

Where:

To know the whole figure's area, we add up both areas:
