Solution in C# (judge verdict: Accepted)

using System;



    class Program
    {
        static void Main(string[] args)
        {
            string[] x = Console.ReadLine().Split(' ');
            int length = int.Parse(x[0]);
            int side = int.Parse(x[1]);

            int area = length * side;
            double circumference = 2 * (length + side);

            Console.WriteLine(area + " " + circumference);
        }
}
