Solution in C# (judge verdict: Accepted)

using System;

namespace AOJ
{
    class Program
    {
        static void Main()
        {
            string[] line = Console.ReadLine().Split(' ');
            int x = int.Parse(line[0]);
            int y = int.Parse(line[1]);

            int area = x * y;
            int leng = 2 * (x + y);

            Console.WriteLine(area.ToString() + " " + leng.ToString());
        }
    }
}
