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
x=raw_input()
y=x.split(" ")
l=int(y[0])
d=int(y[1])
a=l*d
b=2*(l+d)
print(str(a)+str(" ")+str(b))
