Solution in C# (judge verdict: Accepted)

using System;
namespace ITP1_1_C
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] s = Console.ReadLine().Split();
            int a;
            int b;
            a = int.Parse(s[0]) * int.Parse(s[1]);
            b = 2 * (int.Parse(s[0]) + int.Parse(s[1]));
            Console.WriteLine("{0} {1}", a, b);
        }
    }
