Solution in C# (judge verdict: Accepted)

using System;

namespace Rectangle
{
    class Rectangle
    {
        static void Main()
        {
            string input = Console.ReadLine();
            string[] hw = input.Split(' ');
            int[] answer=new int[2];
            answer[0] = int.Parse(hw[0]) * int.Parse(hw[1]);
            answer[1] = int.Parse(hw[0]) * 2 + int.Parse(hw[1]) * 2;
            Console.WriteLine(answer[0] + " " + answer[1]);
            //Console.ReadKey();
        }
    }
