Let P = (a, b), Q = (c, d), and R = (e, f) be any three points in R 2 . Use vectors and the cross product to find a formula, in terms of a, b, c, d, e, and f, for the area of triangle P QR. (One concern here is that the cross product is only defined for for vectors in R 3 , so youâll have to explain how to work around that.)
