Design and implement program that implements the following 3 methods: - Method isValid(...) returns true if the sum of the width and height is greater than 30 boolean isValid(double width, double height){) - Method Area (...) returns the area of the rectangle if it is a valid rectangle .3B double Area (double width, double height){} Method Perimeter(...) returns the perimeter of the rectangle if it is a valid rectangle double Perimeter(double width, double height){} Always remember that in Java and C#, the methods must be public and static The main method should prompt the user to enter the width and height of a rectangle (double values) and uses the methods to print out a message followed by the area and perimeter if the rectangle is valid. Otherwise, it prints out only the message " This is an invalid rectangle." Note: that method isValid(...) is used to validate the input before attempting to compute the area and perimeter.

Define the following methods: computeBaseArea() has one double parameter as a cylinder's radius. The method returns the area of the cylinder's base as a double. The area of the base is calculated by: �� = � ∗ ��2 computeSurfaceArea() has two double parameters as a cylinder's radius and height. The method returns the cylinder's surface area as a double, and uses the computeBaseArea() method to calculate the cylinder's base area.

JAVA CODE PLEASE THANK YOU Rectangle by CodeChum Admin A rectangle can be formed given two points, the top left point and the bottom right point. Assuming that the top left corner of the console is point (0,0), the bottom right corner of the console is point (MAX, MAX) and given two points (all "x" and "y" coordinates are positive), you should be able to draw the rectangle in the correct location, determine if it is a square or a rectangle, and compute for its area, perimeter and center point. To be able to do this, you should create a class for a point (that has an x-coordinate and a y-coordinate). Also, create another class called Rectangle. The Rectangle should have 2 points, the top left and the bottom right. You should also implement the following methods for the Rectangle: display() - draws the rectangle on the console based on the sample area() - computes and returns the area of a given rectangle perimeter() - computes and returns the perimeter of a given rectangle…

Using JAVASCRIPT write an object prototype for a Person that has a name and age, has a printInfo method, and also has a method that increments the persons age by 1 each time the method is called. Create two people using the 'new' keyword, and print both of their infos and increment one persons age by 3 years. Use an arrow function for both methods */ // Create our Person Prototype // Use an arrow to create the printInfo method // Create another arrow function for the addAge method that takes a single parameter // Adding to the age
Background and formula: Ellipse has two types of axis - Major Axis and Minor Axis. The longest chord of the ellipse is the major axis. The perpendicular chord to the major axis is the minor axis, which bisects the major axis at the center as shown in Figure 1. Ellipse is different with circle which has only one radius. There is no simple formula to calculate the exact or accurate value of perimeter of an ellipse. Therefore, we use approximation formulas to calculate the approximate value of an ellipse's perimeter. One of the approximation methods is called Ramanujan Formula as follows: p zn[3(a+b) – Г(За + b) (а + зь)| where a is the semi major axis and b is the semi minor axis of the ellipse, respectively, as shown in Figure 1. be major axis Figure 1.
