Solution in C# (judge verdict: Accepted)

using System;

class Program {
    static void Main( string[] args )
    {
        string[] s = Console.ReadLine().Split( ' ' );
        int a = int.Parse( s[ 0 ] );
        int b = int.Parse( s[ 1 ] );
        Console.WriteLine( ( a * b ) + " " + ( ( a + b ) * 2 ) );
    }
