In the text, we saw a way to explain why the area of the parallelogram in Figure 12.48 is b . h. Anotherway to explain the area formula for parallelograms is to use the area formula for triangles. Show how to subdivide the parallelogram in Figure 12.48 into two triangles. Then use the area formula for triangles to explain why the area of the parallelogram is b . h.
Figure 12.48 Why is the area b . h?
