Solution in C# (judge verdict: Accepted)

using System;


namespace ITP1_1C
{
    class Program

        static void Main()
        {

            int a, b, c, d;
            //a,b,c,d?????´??°??¨???????????????

            string[] str = Console.ReadLine().Split(' ');
            //????????????str?????\?????????????????°?????£??\?????\???????????????????????§?????????(''????????????)

            a = int.Parse(str[0]);
            b = int.Parse(str[1]);
            //???????????¢????????°???(??????????¬¬???????¬¬???)?????´??°??????????????????a,b?????£??\

            c = a * b;
            d = 2 * a + 2 * b;
            //c,d???????????£??\

            Console.WriteLine(c+" "+d);
            //(""??????????????\???????????????)
