Rosie from the Thomas Deacon Academy in
Peterborough U.K. sent in the following accompanied by the
diagrams.
From carrying out this solution, I have found that the more corners
there are to the shape of the lawn the more tiles you
need, as for every corner you need an extra
tile to go in the tip (edge). I found many differant shapes that
could be used for the lawn and tiles and have included the most
interesting and practical ones.
Finlay from Sutton in the U.K. said the
following:
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.
