Explanation:
The Rectangle class was not provided in this question but after a quick online search I was able to find the class code. Due to this I was able to create a test code in the main Method of my program to create a Rectangle object and call it's display() method. The Test code and the output can be seen in the attached image below. While the code below is simply the Main Test Program as requested.
class Brainly {
public static void main(String[] args) {
Rectangle rectangle = new Rectangle(20, 8);
rectangle.display();
}
}
