Part One: Exercise 3

 In this exercise, we modify our code from exercise 2 to prompt a user to enter the dimensions for the length and the width of our rectangle.

You can compare your code to ours below:

          print('*' * 60)

print('A PROGRAM TO CALCULATE THE AREA AND PERIMETER OF A RECTANGLE')

print('*' * 60)

print()

length = float(input('Enter the length of the rectangle: '))

width = float(input('Enter the width of the rectangle: '))

area = length * width

perimeter = 2*(length + width)

print()

print('Length is ',length,'cm')

print('width is ',width,'cm')

print('=' * 25)

print('Area is ',area,'sq. cm')

print('=' * 25)

print('Perimter is ',perimeter,'cm')

print('-' * 25)

 

print('Thank you')

print(f'Area is {area} sq. cm and Perimeter is {perimeter} cm')

 

in the updated code above, I used the float option on the received inputs so as to account for floating-point inputs from the users.

I included a few print() lines so there would be some spacing in the output.

I added the print(‘*’ * 60) line above and below the title to so as to print the string, *, 60 times on the line. I did a similar thing with the print(’=’ * 25) and the print(‘-‘ * 25).

Lastly, I used the f’ format to give a second option for printing the output.
