Dale put the geometry book on the table. He paused before opening it. He’d meant to review the book, since it had been quite a few years since he’d taken a geometry class, and he wasn’t sure he could remember any of the equations. True, they were spelled out in the book, but he still felt woefully unprepared. He couldn’t remember when he’d last used a geometric formula more complicated than calculating the area of a rectangle, but it probably wasn’t since high school. Even then, he’d privately wondered at the utility of it. Homeowner Bob has a lawn with dimensions x by y. What is the most efficient pattern to mow this lawn? Well, Homeowner Bob will probably just get on his lawnmower, crack open a beer, and mow until he’s done. He sure as heck isn’t going to calculate out the most efficient pattern on his kitchen table.
