Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

class Main
{
    public static void main(String[] args)
    {
        Scanner scan = new Scanner(System.in);
        
        int a = scan.nextInt();
        
        int b = scan.nextInt();
        
        System.out.print(a * b);
        
        System.out.print(" ");

        System.out.println((a * 2) + (b * 2));
    }
