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 a, b;
	std::cin >> a >> b;

	std::cout << a*b << ' ' << (a + b) * 2 << std::endl;
