Solution in C# (judge verdict: Accepted)

using System;

class Program
{
    static void Main()
    {
        solveRectanglePloblems();        
    }
    
    static void solveRectanglePloblems()
    {
        string input = Console.ReadLine();
        string[] inputValues = input.Split(' ');
        int a = Int32.Parse(inputValues[0]);
        int b = Int32.Parse(inputValues[1]);
        Console.WriteLine(a * b + " " + 2 * (a + b));
    }
