Solution in C# (judge verdict: Accepted)

using System;

namespace ITP1_1_C
{
    class Program
    {
        public static void Main()
        {
            string [] str = Console.ReadLine().Split(' ');

            Console.WriteLine($"{int.Parse(str[0]) * int.Parse(str[1])} {2 *(int.Parse(str[0]) + int.Parse(str[1]))}");
        }
    }
