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
s = raw_input()
list = s.split()
print str(int(list[0]) * int(list[1])) + " " + str(2 * int(list[0]) + 2 * int(list[1]))
