Solution in C# (judge verdict: Accepted)

using System;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            
            string AB = Console.ReadLine();
            string[] ab = (AB.Split(' '));        //?????????????????§?????????????´???????
            int a = int.Parse(ab[0]);             //????????????int????????°????????????
            int b = int.Parse(ab[1]);
            int x = a * b;
            int y = (a + b) * 2;

            Console.WriteLine(x + " " + y);
        }

    }
