Solution in C# (judge verdict: Accepted)

namespace System
{
    class Program
    {
        static void Main(string[] args)
        {

            var inputted = Console.ReadLine();

            int a = int.Parse(inputted.Split(' ')[0]);
            int b = int.Parse(inputted.Split(' ')[1]);

            int area = a * b;
            int zhou = (a + b) * 2;

            Console.WriteLine(area + " " + zhou);
            Console.ReadKey();
            

        }
    }
