### What is Meant by the Heron’s Formula?

Hero of Alexandria was a great mathematician who derived the formula for the calculation of the area of a triangle using the length of all three sides. It is also termed as Hero’s Formula. Using this formula, we can find the area of different types of triangles suing their sides only. The heron’s formula to find the area of triangle is given by:

Heron’s Formula: A = √[s(s – a)(s – b)(s – c)]

Where “s” is the semi-perimeter of the triangle i.e. s = (a + b + c) / 2

a, b, c are the lengths of three sides of the triangle.
