#include <math.h>

using namespace std;

void Arie(int a,int b,int c)///Se afiseaza in subprogram

{

   double semip,aria;

   semip=(a+b+c)/2;

   aria=sqrt(semip*(semip-a)*(semip-b)*(semip-c));///formula lui Heron

   cout<<aria<<"\n";

}

int Arie2(int a,int b,int c)///Se afiseaza in functia radacina

{

   double semip,aria;

   semip=(a+b+c)/2;

   aria=semip*(semip-a)*(semip-b)*(semip-c);

   return aria;

}

int main()

{

   int a,b,c;

   cin>>a>>b>>c;

   Arie(a,b,c);

   cout<<sqrt(Arie2(a,b,c))<<"\n";

   return 0;
