I have square paving tiles in two different
colors. I want you to design for me a paved
area that is made up of a rectangle in one color
surrounded by a border in the other color.
I want however to use exactly the same number
of tiles of each color and I want the total
paved area to be as large as possible.
How many tiles do I need?
