Answer:
public class Rectangle {
    private double width;
    private double heigth;
    public Rectangle(double width, double heigth) {
        this.width = width;
        this.heigth = heigth;
    }
    public double getWidth() {
        return width;
    }
    public void setWidth(double width) {
        this.width = width;
    }
    public double getHeigth() {
        return heigth;
    }
    public void setHeigth(double heigth) {
        this.heigth = heigth;
    }
    public double perimeter(double width, double heigth){
        double peri = 2*(width+heigth);
        return peri;
    }
    public double area(double width, double heigth){
        double area = width*heigth;
        return  area;
    }
}
class RectangleTest{
    public static void main(String[] args) {
        //Creating two Rectangle objects
        Rectangle rectangle1 = new Rectangle(4,40);
        Rectangle rectangle2 = new Rectangle(3.5, 35.7);
        //Calling methods on the first Rectangel objects
        System.out.println("The Height of Rectangle 1 is: "+rectangle1.getHeigth());
        System.out.println("The Width of Rectangle 1 is: "+rectangle1.getWidth());
        System.out.println("The Perimeter of Rectangle 1 is: "+rectangle1.perimeter(4,40));
        System.out.println("The Area of Rectangle 1 is: "+rectangle1.area(4,40));
        // Second Rectangle object
        System.out.println("The Height of Rectangle 2 is: "+rectangle2.getHeigth());
        System.out.println("The Width of Rectangle 2 is: "+rectangle2.getWidth());
        System.out.println("The Perimeter of Rectangle 2 is: "+rectangle2.perimeter(4,40));
        System.out.println("The Area of Rectangle 2 is: "+rectangle2.area(4,40));
    }
}
Explanation:
- Firstly A Rectangle class is created with two fields for width and heigth, a constructor and getters and setters the class also has methods for finding area and perimeters
- Then a RectangleTest class containing a main method is created and two Rectangle objects are created (Follow teh comments in the code)
- Methods to get height, width, area and perimeter are called on each rectangle object to print the appropriate value
