The Heron's formula, also known as Hero's formula or Héron's formula, is a mathematical formula used to calculate the area of a triangle when the lengths of all three sides are known. This formula is named after the ancient Greek mathematician Heron of Alexandria, who first recorded this formula in his book "Metrica" in the 1st century AD. Mathematically, the Heron's formula is expressed as follows: Area = √(s(s-a)(s-b)(s-c)) Here, a, b, and c represent the lengths of the triangle's sides, and
