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)

def squareArea(x, y)
	return x * y
end
def squareSide(x, y)
	return (x * 2) + (y * 2)
end

input = gets.chomp
a, b = input.split(' ').map(&:to_i)

puts sprintf('%d %d', squareArea(a, b), squareSide(a, b))
