Solution in C# (judge verdict: Wrong Answer)

using System;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            string input = Console.ReadLine();
            string[] dw = input.Split(' ');

            int length = Int32.Parse(dw[0]) * Int32.Parse(dw[1]);
            int area = (Int32.Parse(dw[0]) + Int32.Parse(dw[1])) * 2;

            Console.WriteLine("{0} {1}", area, length);
        }
    }
}
