import java.util.Scanner;

class Main{
     public static void main(String[] args){

        Scanner as = new Scanner(System.in);
        int a = as.nextInt();
        int b = as.nextInt();

        int ab=a*b;
        int apb=(a*2)+(b*2);
        
 
        System.out.println(ab+" "+apb);
 
 
   }
