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)

def rect(a,b):
    return a*b, 2*(a+b)
n = input()
s = n.split()
a = int(s[0])
b = int(s[1])
area, perimeter = rect(a,b)
print(area,perimeter)
