Solution in C# (judge verdict: Accepted)

using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            String x = Console.ReadLine();

            String[] array  = x.Split(' ');

            int height = int.Parse(array[0]);
            int side = int.Parse(array[1]);
            int syu = height * 2 + side * 2;
            int area = height * side;
            
            //???????????¨???
            Console.WriteLine(area + " " + syu);
        }
    }
