Heron's Formula Calculator

Heron's formula calculator calculates the area for any triangles base on three sides of the triangle.

The regular area of a triangle is calculated by base and height. Heron's formula is calculated by three sides of a triangle without knowing the height.

Heron's Formula

Following is the Heron's formula:

Area=√s(s-a)(s-b)(s-c), where

s = semi-perimeter of the triangle
a = one side of the triangle
b = second side of the triangle
c = third side of the triangle

The forumla of semi perimeter of triangle:
s=(a+b+c)/2.
The perimeter of a triangle is calculated by adding three sides altogether, therefore semi perimeter is calculated as half of the perimeter.
