Exercise 1: Make a Rectangle Class

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:

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

It’s expected to print:

5
10
50
