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
tmp = raw_input().split()
a = int(tmp[0])
b = int(tmp[1])
s = a * b
l = 2 * (a+b)

print "%d %d" % (s, l)
