How do i calculate the total composite area for these figures?

For number 13, you can break apart the shape into regular quadrilaterals.
For number 14, you can also break apart the shape. Find the area of the half circle (there are two quarter circles).
For number 15, find the area of the full triangle, then find the area of the circle. Then subtract the circle from the triangle.
