# Heron's Formula

In geometry, Heron's formula provides an alternative method for finding the area of a triangle. The formula is very useful when only the lengths of the sides are known.

This formula is credited to mathematician Heron of Alexandria. The formula is a special case of Brahmagupta's formula.

The proof and demonstration of Heron's formula can be done from algebra and elementary consideration of geometry. Also applications of the law of cosine help to derive the Heron's formula for the area of a triangle in which all sides of the triangle are given. One of the numbers found in this formula is the semiperimeter of a triangle, which defined as one half the perimeter.

In this article, we are going to study about Heron's formula and its derivation in detail.
