In high school mathematics textbooks (people teach the compulsory second book, p. 90) there is such a probe and discovery of the topic: one day, the famous magic master Mr. Chiu took a side carpet length of 1.3 meters to find the carpet Carpenter Master , Requiring that the square carpet be converted into a rectangle 0.8 meters wide and 2.1 meters long.
