Solution in C# (judge verdict: Accepted)

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] s = Console.ReadLine().Split(' ');

            int tate = int.Parse(s[0]);
            int yoko = int.Parse(s[1]);

            int area = tate * yoko;
            int rect = (tate + yoko )* 2;

            Console.WriteLine(area + " "+rect);

            //int n = int.Parse(s);

            //n = (int)Math.Pow(n, 3);

            //Console.WriteLine(n);
        }
    }
