Heron's Formula Calculator
Calculate the area of a triangle using Heron's formula, which uses the lengths of all three sides.
Heron's Formula
Formula
A = √(s(s-a)(s-b)(s-c))
where s = (a + b + c)/2 is the semi-perimeterSteps
- Calculate the semi-perimeter: s = (a + b + c)/2
- Calculate the area: A = √(s(s-a)(s-b)(s-c))
Note: Heron's formula allows you to calculate the area of a triangle when you know the lengths of all three sides, without needing to know the height or angles.
