OG详解-OG1 数学1 Q23

Choice D is correct. Since the number of yards in  1 mile is  1,760 , the number of  square yards in 1 square mile is  (1,760)(1,760)= 3,097,600 . Therefore, if the area of the town is 4.36  square miles, it is  4.36(3,097,600)= 13,505,536, in square yards.
Choice A is incorrect and may result from dividing the number of yards in a mile by the square mileage of the town. Choice B is incorrect and may result from multiplying the number of yards in a mile by the square mileage of the town. Choice C is incorrect and may result from dividing the number of square yards in a square mile by the square mileage of the town.
