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 Ruby (judge verdict: Accepted)

lb = gets.split(" ")
length = lb[0].to_i
breadth = lb[1].to_i

area = length * breadth
perimeter = 2 * length + 2 * breadth

puts (area.to_s + " " + perimeter.to_s)
