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
str = raw_input()
a = str.split(' ')

n1 = int(a[0])
n2 = int(a[1])

print n1 * n2, (n1 + n2) * 2
