Riley has a farm on a rectangular piece of land that is 200 meters wide. this area is divided into two parts: a square area where she grows avocados (whose side is the same lenght of the farm), and the remaining area where she lives. every week, riley spends $3 per square meter on the area where she lives, and earns $7 per square meter from the area where she grows avocados. that way, she manages to leave some money every week.
