Heron's formula is a method used in geometry to find the area of a triangle when only the lengths of its three sides are known. It was named after Hero of Alexandria, who used it for this purpose.
Formula:
A = √(s
(s-a)
(s-b)
(s-c))
where:
- A is the area,
- s is the semi-perimeter (half the perimeter),
- a and b are the lengths of two sides of the triangle,
- c is the
