Write a program to get three sides of a triangle and calculates its area using the formula:
area = sqrt[s(s-a)(s-b)(s-c)] where s = (a + b + c) / 2. Use math library to find the square
root of values.
Source code:
{
float a,b,c,s,A;
cout<<"enter sides of triangle\n";
cin>>a;
cin>>b;
cin>>c;
s=(a+b+c)/2;
A=sqrt(s*(s-a)*(s-b)*(s-c));
