From carrying out this solution, I have found that the more corners

The solution to a rectangular lawn is:
Mathematical terms:$(n x 2) + (X x 2) + 4$
English terms: if you multiply on side of the lawn by two and add
it to a different length side multiplied by two, and then add four
it will equal the number of tiles around the lawn.
Thank you, both of you for these good
