A right triangle can be found by using 1/2bh but since there are two right triangles forming one triangle, you can do the base * height and get the answer of the entire triangle.

For the trapezoid, you will need to do the same thing and split it into another right triangle (there should be one on each end) and then find the area of the square in the center of them by calculating height * width - base of both triangles
For a triangle, apply:
Area = 1/2×base×height
