I would say 28 square inches. Imagine that we divide the number and we get 4 and seven. your average paperback book is about 4 inches wide and 7 inches tall. If we multiply it back, we get 28 square inches. Hope it helps! -Lacy
It would be centimeters becuase square inches is a very large area, much larger than a typical book. Therefore, the paperback book would most likely be 28 square centimeters
