Solution in C# (judge verdict: Accepted)

using System;
class P
{
public static void Main()
{
            //????????????????????????
            string x = Console.ReadLine();
            var split = x.Split(' ');

            int a = Int32.Parse(split[0]);
            int b = Int32.Parse(split[1]);

            //??¢???
            int S = a * b;
            //??¨???
            int L = 2 * a + 2 * b;

            //??????
            Console.WriteLine(S + " " + L);
}
