Explore OOP in Ruby to gain a deeper understanding of Ruby objects, Ruby methods, and Ruby classes, enabling you to solve multiple problem sets with an object-oriented approach.

Module Overview
Ruby is a smart, functional, and object-oriented programming language that blends the best features of scripting power with user-friendly syntax. In this module, we’ll dive into OOP in Ruby with hands-on practice using interactive exercises and illustrations. We'll start by creating and managing Ruby objects. Next, we’ll explore Ruby methods and blocks, essential tools in Ruby programming. Finally, we'll delve into Ruby classes and how they are used to implement OOP principles.

Ruby OOP (Object-Oriented Programming)

## Problem statement

Write a `Rectangle` class with `height` and `width` attributes and an `area()` instance method.

- Populate these attributes through the `initialize(height, width)` method.
- Define attribute readers for these attributes.

### Example

With your definition, consider the following code:

```ruby
rect = Rectangle.new(5,10)
puts rect.height
puts rect.width
puts rect.area()
```

It’s expected to print:

```ruby
5
10
50
```
