I guess we did the same for the most part by using a smaller example before a formula could be found. By starting with a rectangular grid, it makes sense to think of a more efficient way by using a square grid.
Alice, Your works is neat and easy to follow and understand. We have similar solving strategies. We all start from using smaller sexample, ex: 1 square, 2 squares, 3 squares.... and try to find the pattern and generalized formula. I think this is a really useful and common strategy to solve this kind of problems :)
