Solution in C# (judge verdict: Accepted)

using System;
class AOJ
{
    public static void Main()
    {
        String[] st = System.Console.ReadLine().Split(' ');
        int a=  int.Parse(st[0]);
        int b;
      b=  int.Parse(st[1]);
        int c = a + a + b + b;
        Console.WriteLine("{0} {1}",a*b,c);
    }
