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 sys
input_arr = map(int,sys.stdin.readline().split())
print input_arr[0]*input_arr[1], 2*(input_arr[0]+input_arr[1])
