'''
In this exercise we will practice using functions that return multiple values 
and see how to store multiple values. One common reason to return multiple 
values with one function is that the outputs require the same input parameters 
and both output values are always required for our use case. In other cases 
one of the outputs might be an intermediary output of the final output, but the 
intermediary is still useful to us.

In this example you will work with a function that calculates the perimeter and 
area of a rectangle. The goal is to help you understand the utility of returning 
multiple values from a function and how to correctly assign these values to 
different variables.

Exercise A:
You are provided with a function `calculate_rectangle` that calculates both the 
perimeter and area of a rectangle given its length and width.
Your task is to call the function, capture the returned values, and correctly 
assign them to the variables perimeter and area.
Print out the results to verify that you have correctly handled the function's output.
'''

def calculate_rectangle(length, width):
    perimeter = 2 * (length + width)
    area = length * width
    return perimeter, area

# Given parameters
length = 5.0  # meters
width = 3.0   # meters

# Your code here

'''
Exercise B:
Do the same as in A, but with a slightly different function.
'''

def calculate_rectangle_list(length, width):
    perimeter = 2 * (length + width)
    area = length * width
    return [perimeter, area]

# Given parameters
length = 5.0  # meters
width = 3.0   # meters

# Your code here
