I just have to say something about a walkway!!

I think of a walkway as a sidewalk AROUND grass. When I first read it, I thought it was perimeter. I have been teaching for 20 years and quite honestly very confident in my math ability. I realized it was area because it said 54 square feet. I did have to read the question twice.
