Solution in C# (judge verdict: Accepted)

using System;

namespace AOJ
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] a = new int[2];
            string[] s = Console.ReadLine().Split(' ');
            a[0] = int.Parse(s[0]);
            a[1] = int.Parse(s[1]);
            int b = a[0] * a[1];
            int c = 2 * (a[0] + a[1]);
            Console.WriteLine(b + " " + c);
        }
    }
