Hello!

You find the area of all three shapes and add them together

We can do the one on the left first

To find the area we multiply the sides

8 * 7 = 56

The one on the left has an area of 56 ft squared

Now lets do the one on the right

8 * 7 = 56

The one on the left has an area of 56 ft squared as well

Finally lets do the one in the middle

We first have to find the length

8 + 12 = 20

Now we multiply

20 * 20 = 400

The middle one has an area of 400ft squared

Now we add them together

56 + 56 + 400 = 512

The answer is 512ft squared

Hope this helps!
