Solution in C# (judge verdict: Accepted)

using System;

namespace AOJ_Intro_Rectangle
{
	class MainClass
	{
		public static void Main (string[] args)
		{
			int x, y;
			string[] inputdata;
			inputdata = Console.ReadLine ().Split(" ".ToCharArray());
			x = int.Parse (inputdata [0]);
			y = int.Parse (inputdata [1]);

			Console.WriteLine ("{0} {1}",x * y, 2*x + 2*y);
		}
	}
