Answer: Let the Vertices of the Triangle are:

             (Ax, Ay) = (5,4)

             (Bx, By) = (-2,4)

             (Cx,Cy) = (2,-6)

The area of the triangle = Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By) / 2

                                         = 5[-2 - (-6)] + (-2)[(-6) - 4] + 2[4 - 4] / 2

                                         = 5[-2 + 6] + (-2)[-6-4] + 2*0 / 2

                                         = 5*4 + (-2)*-10 + 0 / 2

                                         = 20 + 20 / 2

                                         = 40 / 2

                                         = 20
