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
dato=raw_input()
a=int(dato[:dato.find(' ')])
b=int(dato[dato.find(' '):])
A=str(a*b)
P=str(2*a+2*b)
print A+" "+P
