WebThen $\sin A$, $\sin B$, and $\sin C$ are actually the lengths of the sides opposite that three angles---that's essentially the law of sines. The area of any triangle is the product of the lengths of two sides times the sine of the angle between them, divided by $2$. So the area in this case is $(\sin A\sin B\sin C)/2$.
