Area of triangle by Heron's formula
Beginning status (before activation):
1 *
2 *Let the sides of a triangle be a=13, b=14, and c=15.
3 *The area of the triangle can be calculated by Heron's formula
4 *Area=sqrt(p*(p-a)*(p-b)*(p-c))
5 *where p equals the half of the perimeter p=(a+b+c)/2 and
6 *where sqrt() denotes the square root.
7 *Hence Area=
8 *
