$Let\enspace Z = a +ib,\enspace W = c + id\enspace \text{be points on the complex plane.}$
Show that the area of the triangle of vertices $0, Z, W$ is
$$\frac{1}{2}|Im(\overline{Z}W)|"$$
Hi, I'm having difficulties trying to show this. Can someone give me a hint?
Hint:
$$\frac{\text{base}\times\text{height}}{2}$$
