C++ :

#include<iostream>
using namespace std;
inline int calArea(int length,int width){
  return length*width;
}
inline int calPerimeter(int length,int width){
  return 2*(length+width);
}
int main(){
int length,width;
  cin>>length>>width;
  int area=calArea(length,width);
  int primeter=calPerimeter(length,width);
  cout<<area<<' '<<primeter<<endl;
  return 0;
}
