Write a Java program to calculate the area and perimeter of a rectangle. The area of a rectangle is its length multiplied by its width. The perimeter is the distance around the outside of the rectangle. The logic for the problem is specified below. The program/class name is Rectangle, so the file name must be Rectangle.java.
Multiplication in Java uses a "*" like in Basic.
Length ? 10 Width ? 5 Area = 50 Perimeter = 30
Rectangle()
Input length, width area = length * width
perimeter = (length + width) * 2
Display area, perimeter
STOP

A shop owner requires a program to calculate the GST payable on items purchased. The GST is one-tenth of the pre GST price. For example, if the pre-GST price was $100 then the GST is $10 and the price including GST is $110. The user is to input the pre-GST price and the program is to display the GST and the final price including GST.
Run Pre GST Price ($) ? 100 GST = $10.00 Price Including GST = $110.00
Run Pre GST Price ($) ? 5.50 GST = $0.55 Price Including GST = $6.05
