Heron's Formula

The formula given by Heron about the area of a triangle, is also known as Heron’s formula. It is stated as:
**Area of triangle = √s x (s-a) x (s-b) x (s-c)**

where a, b and c are the sides of the triangle, and s = semi-perimeter, i.e., half the
**perimeter of the triangle = (a + b + c)/2**

Area of a quadrilateral whose sides and one diagonal are given, can be calculated by dividing the quadrilateral into two triangles and using the Heron’s formula.
