Write a program which calculates the area and perimeter of a given rectangle.

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{
    static public void main(String[] av){
	Scanner sc = new Scanner(System.in);
	int a = sc.nextInt();
	int b = sc.nextInt();
	int x = a*b;
	int y = 2*a + 2*b;
	System.out.println(x+" "+y);
    }
}
