Yes Jessilyn. It is perfectly fine. In fact you have made me wonder why I even bothered to bounce the ratio up from 5:9 to 15:27. Duh me lol. Well done.

When you "push" both grass patches together, thereby covering the pavement, the right zigzag edge of the left grass patch will fit in nicely with the left zigzag edge of the right grass patch. The final product is a grass patch measuring 27m by 20m since the 3-m-wide pavement has been covered.
