China's land area is about 9.6 million square kilometers, and the area drawn on the 1:10 million scale map is about () A. 960 square kilometers B. 960 square meters C. 960 square decimeters D. 960 square centimeters
9.6 million square kilometers = 9.6 × 1016 square centimeters, if the area drawn on the map is about x square centimeters, then x: 9.6 × 1016 = (1:10 million) 2, the solution is x = 960, then the area drawn on the map is about 960 square centimeters
