Heron's formula calculator
Given the three lengths of any triangle, Heron's formula calculator will compute the area for you
Instructions for using the calculator
Note that the triangle above is only a representation of a triangle.
Your triangle may look different. However, all it takes to find the area is to enter the lengths of a, b, and c.
If the area = 0, this means that the lengths you entered gave a straight line instead of a triangle.
This happens when the length of one side (the longest side) equal to the sum of the other two sides
If it says NaN, the values you entered did not make a triangle
You make a triangle when the length of
any side is smaller than the sum of the other two sides
