👉 Heron's formula, often used in calculating areas of triangles, involves finding the area of a triangle when given three sides (or two pairs of lengths) and then using Heron's formula:
Area = √[s(s - a)(s - b)(s - c)],
where s is the semi-perimeter of the triangle. This formula can be used for any set of three sides or two pairs of lengths, depending on the type of triangle you're calculating.
