2. Mowing Madness
Matt, a boy in our neighborhood, run a mowing business in the summer.
When Matt complained to his father that he was bored while mowing, his father quickly replied, "How about exercising
your brain while you work on the lawns?
I imagine there are many ways to look at mowing the lawns mathematically."
Since Matt loves a math challenge, he decided to give this a try.
For one week, he decided he would cut all lawns by starting at the outside part of the lawn and mowing a path
completely around the outside edge.
Then, he would mow a second path around the remaining portion of the lawn, and he would continue "Matt-Mowing"
he competed the entire lawn.
While he mowed, Matt would create additional challenges for himself by
calculating the dimensions of the rectangles he was mowing, as well as predicting the
dimension of the last rectangle he would mow to complete the job.

3. What else do you need to know?

Question:
