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
b = raw_input()
a = b.split()
#print a[1]
x = int(a[0])
y = int(a[1])
s = x * y
l = 2 * x + 2 * y
print s,l
