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)

s=input()
x=s.split()
a=int(x[0])
b=int(x[1])
if 1<=a<=100 and 1<=b<=100:
    print(a*b,a*2+b*2)
