Solution in C# (judge verdict: Accepted)

using System;

public class Rectangle
{
    //????????¢?????¢????????¨?????????????±???????
    static void Main(string[] args)
    {
        /*---??£?¨???¨---*/
        int a;
        int b;
        string[] square;
        /*---??£?¨???¨---*/

        /*???????????????????????§????????????*/
        square = Console.ReadLine().Split(' ');
        a = int.Parse(square[0]);
        b = int.Parse(square[1]);

        /*????????¢?????¢????????¨?????????????????§??????*/
        Console.WriteLine("{0} {1}",a*b ,2*a + 2*b);
    }
