a new mystery shape
260 Chapter 6
Landowners, unite
Just when all the lawns seemed under control, Edward ran into a little snag.
He turned up at a customer’s house to find that he has been buying up
adjacent land. The neat rectangular lawn that Edward had been mowing
for months has been transformed into…something else.

After:
It’s going to take longer to mow and edge this new lawn, and

28 meters
24 meters
24 meters
28 meters
53 meters
The lawn was originally a tidy
rectangle. Super easy to mow,
and calculating charges was a
snap!
The lawn is definitely
larger. It still has four
sides, but it’s not a shape
we’ve seen before.
