Solution in C# (judge verdict: Wrong Answer)

using System;

namespace Getting_Started
{
    class Rectangle

        static void Main(string[] args)
        {
            var line = Console.ReadLine();
            var token = line.Split(' ');
            int a = int.Parse(token[0]);
            int b = int.Parse(token[1]);
            Console.WriteLine(a*b+" "+2*a+2*b);
        }
    }
