Rectangles and Wheels

Great work recruit. Now for the mental part of the challenge. And I do mean ‘mental’ as in hard, not ‘mental’ as in crazy good fun. In fact, this probably won’t be any fun at all. No-one likes math.

I need you to add the number of complete rectangles in the roof rack of the car, the number of wheels on the car, and the number of bolts holding the window in place. When you’re done, this number will form your next clue. Write it down with the other two, and then get back to the grass without touching the water.
