using namespace std;
int area(int);
int area(int,int);
float area(float);
float area(float,float);
int main()
{

cout<<"Area of square is"<
cout<<"\nArea of rectangle is "<
cout<<"\nArea of circle is "<
cout<<"\nArea of triangle is "<
}
int area(int s)
{
return(s*s);
}
int area(int l,int b)
{
return(l*b);
}
float area(float r)
{
return(3.14*r*r);
}
float area(float bs,float ht)
{
return((bs*ht)/2);
}
