Given information:
The formula
Calculation:
A simple concave
It is always possible to partition a non convex polygon into a set of convex polygons, and as all convex polygons follows theorem 3-13.
Thus, it is possible to apply the formula
b)
Whether the reasoning leading up to theorem 3-13 apply to figure.
b)
