Solution in C# (judge verdict: Accepted)

using System;
class rectangle
{
    public static void Main()
    {
        int a, b;
        string[] rec = Console.ReadLine().Split(' ');
        a = int.Parse(rec[0]);
        b = int.Parse(rec[1]);
        int c = a * b;
        int d = 2 * (a + b);
        Console.WriteLine("{0} {1}",c,d);
    }
