Problem:
Rectangle

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

Print the area and perimeter of the rectangle in a line. The two integers should be separated by a single space.

Constraints

1 ≤ a, b ≤ 100

Sample Input 1

3 5

Sample Output 1

15 16

Solution in Python3 (judge verdict: Accepted)

l = input().split(' ')
l = list(map(int, l))

h, w = l[0], l[1]

area = h * w
length = 2*h + 2*w

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