find the area of a square in ruby

To find the area of a square in Ruby, you can simply use the formula side length * side length. Here's an example:

main.rb
side_length = 5
area = side_length * side_length
puts "The area of the square is #{area}."
91 chars
4 lines

This code sets the side_length variable to 5, calculates the area using the formula, and then prints the result to the console using string interpolation. You can easily modify this code by changing the value of side_length to fit your specific needs.
