Solution in C# (judge verdict: Accepted)

using System;

namespace helloworld {
    class Program {
        static void Main(string[] args) {
            var input = Console.ReadLine();
            var a = int.Parse(input.Split(' ')[0]);
            var b = int.Parse(input.Split(' ')[1]);

            var area = a * b;
            var length = 2 * (a + b);

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