Question

6.6 Lab: Rectangle Class

This program creates a Rectangle object, then displays the rectangle's

• length,

• width, and

• area

  Change this program to calculate and display the rectangle's

• perimeter.

Example:

In feet, how wide is your house? 20
In feet, how long is your house? 25
The house is 20.00 feet wide.
The house is 25.00 feet long.
The house has 500.00 square feet of area.
The house has 90.00 feet of perimeter.
