Rectangle Perimeter
This function should take two positive numbers (length and width) as inputs and return the perimeter of a rectangle.
Input: Two integers (int).
Output: Integer (int).
Examples:
assert rectangle_perimeter(2, 4) == 12 assert rectangle_perimeter(3, 5) == 16 assert rectangle_perimeter(10, 20) == 60 assert rectangle_perimeter(7, 2) == 18
How it’s used:
- in architectural and engineering applications for calculating the perimeter of buildings or rooms;
- in computer graphics to calculate the perimeter of a rectangle on a screen.
Preconditions:
- length, width ∈ R;
- length, width > 0.
