Solution in C# (judge verdict: Accepted)

using System;

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

		// calc
		var l = (a + b) * 2;
		var s = a * b;

		Console.WriteLine(string.Format("{0} {1}", s, l));
	}
