In Exercises 21-24, a, b, and c are noncollinear points in ℝ2 and p is any other point in ℝ2. Let Δabc denote the closed triangular region determined by a, b, and c, and let Δpbc be the region determined by p, b, and c. For convenience, assume that a, b. and c are arranged so that det
21. Show that the area of Δabc is det
