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
A = raw_input()
B = [int(i) for i in A.split()]
print B[0]*B[1], 2*(B[0]+B[1])
