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)

t = input()
t = t.split()
a = int(t[0])
b = int(t[1])

def P(x,y):
 print(x*y,2*(x+y))
 return 0

P(a,b)
