How it works

Calculate the area of a triangle given its side lengths.

The Formula

Area = √(s * (s - a) * (s - b) * (s - c))
where s = (a + b + c) / 2

Worked Example

1. Example: Find the area of a triangle with side lengths 3, 4, and 5.

   Given a triangle with side lengths a = 3, b = 4, and c = 5, calculate its area using Heron's formula.

Tips, Assumptions & Limitations

• Make sure to enter valid side lengths.
