The Heron’s Formula Calculator is an online tool tha calculates the area of a triangle, provided the sides of the triangle. BYJU’S Heron’s Formula Calculator is a tool which makes calculations of triangle’s area, simple and interesting. If the inputs are given then it can easily show the result for the given number.

## How to use the Herons Calculator?

To use Herons calculator we can follow the below given steps:

Step 1: Mention the lengths of the  three sides of the triangle (unit of the length is not required)

Step 2: Click on the “Calculate” button”

Step 3: The values of semi-perimeter and area of triangle will appear on the screen.

## What is Herons Formula?

Heron’s formula is a formula used to calculate the area of the triangle, when the length of all the three sides are given. The Hero’s formula is given by:

Area of triangle = √[s(s-a)(s-b)(s-c)]

where a,b and c are the lengths of sides of triangle

and s is the semi-perimeter of triangle

s = (a+b+c)/2
