The semiperimeter of a figure is one half of the perimeter, or $\frac{P}{2}$, where $P$ is the total perimeter of a figure.


Applications

The semiperimeter has many uses in geometeric formulas. Two well known examples are Heron's formula and Brahmagupta's formula. It frequently shows up in triangle problems.
