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
#include<iostream>

int main()
{
  double a,b;

  std::cin>>a>>b;
  std::cout<<a*b<<" "<<(a+b)*2<<'\n';

  return 0;
}
