Problem 91
The sides of a square are each \(16 \mathrm{cm}\) long. A second square is inscribed by joining the midpoints of the sides, successively. In the second square, we repeat the process, inscribing a third square. If this process is continued indefinitely, what is the sum of all of the areas of all the squares?
