Solution in C# (judge verdict: Accepted)

using System;

public class Test
{
    
	public static void Main()
	{
	    int a,b,m,l;
	    string[] s = Console.ReadLine().Split();
	    a = int.Parse(s[0]);
	    b = int.Parse(s[1]);
	    m = a * b;
	    l = a *2 + b *2;
	    Console.WriteLine("{0} {1}",m,l);
	    return ;
