Given the code below

public class Rectangle {

private double length;

private double width;

// setters and getters

public double getLength(){???}

public void setLength(???){???}

public double getWidth(){???}

public void setWidth(???){???}

// object method

????calculateArea(){????}

????isSquare(){????}

}

a. Complete the appropriate Getter methods.

b. Complete the appropriate Setter methods - including the parameters required

c. Complete a method so that the method calledcalculateArea() returns the area of the rectangle.

d. Complete a method so that the method calledisSquare() returns true if width is equal to length, otherwise return false.
