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 Python (judge verdict: Accepted)

line = raw_input()
lis = line.split()
a = int(lis[0])
b = int(lis[1])
s = a * b
len = 2 * (a + b)
print str(s) + " " + str(len)
