In two villages, A and B, the owner's land of A is about four times that of B, and the shape of the land is close to a square. One day, two car owners made a bet. Car owner B said, "It takes me 1.5 hours to ride my own land and 3.5 hours to run your land." The owner of Jiezhuang did not believe it and said, "If you run back in 3.5 hours, then give me your manor." B said, "It's a deal." Let the queen drive the horse away. Who do you think is the winner? Why? Answer: Because the shape of the land is close to a square, it can be considered similar. According to the fact that the area ratio is equal to the square of the similarity ratio, because S A =4S B, the perimeter of A is about twice that of B.. Then B needs 1.5h to run around his own land, and 3h to run around A's land. Within the range of 3.5h, then B wins.
