Solution in C# (judge verdict: Accepted)

using System;

namespace ITP_1_C{
    class Program{
        static void Main(){

            int a,b;
            string[] str = Console.ReadLine().Split(' ');//2?????\?????????????????????????????\????????????
            a = int.Parse(str[0]);
            b = int.Parse(str[1]);

            //??¢???
            int menseki = a * b;
            //??¨?????????
            int syuu = a * 2 + b * 2;

            Console.WriteLine(menseki + " " + syuu );
        }
    }
