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 Ruby (judge verdict: Accepted)

input = STDIN.gets
x, y = input.split(" ")
rect = x.to_i * y.to_i
perimeter = x.to_i * 2 + y.to_i * 2
print rect, " ", perimeter, "\n"
