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()
for i, b in enumerate(a.split()):
	if i==0:
		x=int(b)
	else:
		y=int(b)
print x*y,x*2+y*2
