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)

input = gets.split(' ')
area = input[0].to_i * input[1].to_i
perimeter = (2 * input[0].to_i) + (2 * input[1].to_i)
puts area.to_s + ' ' + perimeter.to_s
