Write a program which calculates the area and perimeter of a given rectangle.

Input

The length a and breadth b of the rectangle are given in a line separated by a single space.

Output

3 5

Sample Output 1

15 16

Solution in Python3 (judge verdict: Accepted)

# coding: utf-8

list = input().rstrip().split(" ")

area = int(list[0])*int(list[1])
length = int(list[0])*2 + int(list[1])*2

print(str(area) + " " + str(length))
