Solution in C# (judge verdict: Accepted)

public class A
{
    public static void Main()
    {
        string str = System.Console.ReadLine();
        string[] istr = str.Split(' ');
        int a = int.Parse(istr[0]);
        int b = int.Parse(istr[1]);
        System.Console.WriteLine((a * b) + " " + (a + a + b + b));
    }
