Heron's Formula for SSS Triangle Area

The area of a triangle given its three side lengths (a, b, c) is calculated using Heron's formula:

Semi-perimeter (s): s = (a + b + c) / 2

Area (A): A = √(s(s - a)(s - b)(s - c))

Where:

  • a, b, c represent the lengths of the three sides of the triangle.
  • s is the semi-perimeter of the triangle.
