How to do Area of this figure?

Answer:
I don't want to do the problem for you but
Step-by-step explanation:
First you have to divide the figure into 2 parts. Then, you find the area of both the rectangles. You will also have to subtract the 8 from 12 which is 4 and after that you can subtract 5 from 18 because in a rectangle the opposite sides are the same. After you do those step you find the area of the rectangles.
Formula: Area= base * height
After you have to add both of the area up.
And that it!!
Hope this helps!! :)
