Let $\triangle ABC$ be a triangle whose sides are $a$, $b$ and $c$ opposite vertices $A$, $B$ and $C$ respectively.

Then the area $\AA$ of $\triangle ABC$ is given by:

- $\AA = r s$

where:

- $r$ is the inradius of $\triangle ABC$
- $s = \dfrac {a + b + c} 2$ is the semiperimeter of $\triangle ABC$.
