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
n=raw_input()
k=n.split(" ")
a=int(k[0])
b=int(k[1])
print a*b ,
print (a+b)*2
