Solution in C# (judge verdict: Accepted)

using System;

class Rectangle{
      static void Main(string[] args){
      	     string[] str = Console.ReadLine().Split(' ');
      	     int n = int.Parse(str[0]);
	     int m = int.Parse(str[1]);
	     int s = n * m;
	     int l = 2*n + 2*m;
	     Console.WriteLine("{0} {1}",s,l);
	     }
}
