B) We can use a similar trick to find the area of a trapezoid using the area of triangles. Trace the trapezoid on the next page (or draw a new one) and show how to divide it into two triangles. This time, the triangles will have the same height but different bases. Then, use the area of a triangle to get the formula for the area of the parallelogram. a
