So to make it easier, you can break the shape up in a smaller shape. So now it'll look like 2 big rectangles on each side with a small rectangle in the middle. Now you can find the area.
For the big rectangle on the left:
5 × 15 = 75
For the big rectangle on the right:
5 × 15 = 75
For the small rectangle in the middle:
It doesn't say what the length is but if you subtract 8 from 15, that's what the length will be.
