Solution in C# (judge verdict: Wrong Answer)

using System;


    class Program
    {
        static void Main(string[] args)
        {
            int tate = 0, yoko = 0, menseki = 0, syu = 0;
            string[] data = Console.ReadLine().Split();//????????\?????????
            tate = int.Parse(data[0]);
            yoko = int.Parse(data[1]);
            menseki = tate * yoko;//??¢???????±?????????????
            syu = (tate * 2) + (yoko * 2);//??¨?????????????±?????????????
            Console.WriteLine("{0},{1}", menseki, syu);

        }
   }
