Before 2017, a smart phone manufacturer’s phones had a diagonal length of 5.8 inches and an aspect ratio of 16:9. In 2017, they released a new phone that also had a 5.8-inch diagonal length, but an aspect ratio of 18.5:9. Some customers complained that the new phones had a smaller screen. Were they correct? If so, how much smaller was the new screen compared to the old screen?
