Constraints

* 1 ≤ a, b ≤ 100

Input

The length a and breadth b of the rectangle are given in a line separated by a single space.

Output

Print the area and perimeter of the rectangle in a line. The two integers should be separated by a single space.

Example

Input

3 5


Output

15 16
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();
int c =a*b;
int d =2*(a+b); 
System.out.println(c + " " +d);
    }
}
