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
#include <iostream>
int main() {
	int x, y;
	std::cin >> x >> y;
	std::cout << x*y << " " << 2*x+2*y << "\n";
	return 0;
}
