Project 2-3 Rectangle Calculator

Create an application that calculates the area and perimeter of a rectangle. Then using a loop, ask the user if they want to continue. If yes then repeat the input, processing, and output. If no then end the program.

Console

Welcome to the Area and Perimeter Calculator

Enter length: 100

Enter width: 200

Area: 20000.0

Perimeter: 600.0

Continue? (y/n): y

Specifications

The formulas for calculating area and perimeter are:

area = width * length perimeter = 2 * width + 2 * length

The application should accept decimal entries like 10.5 and 20.65.

Assume that the user will enter valid numeric data for the length and width.

The application should continue only if the user enters y or Y to continue.

Input:

Print the header "Welcome to the Area and Perimeter Calculator"

Ask the user to enter a length

Ask the user to enter a width

Processing:

Save the length and width in variables

Calculate the area and save the results in a variable

Calculate the perimeter and save the results in a variable

Output

Print the area and perimeter per the example
