Correct answer: A (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice A is correct. It’s given that the length of each side of a scale model is 1 10 times the length of the corresponding side of the actual floor of a ballroom. 1 2 1 Therefore, the area of the scale model is b 10 l , or 100, times the area of the actual floor of the ballroom. It’s given that the area of the floor of the ballroom is 600 square meters. Therefore, the area, in square meters, of the scale model is 1 600 ` 100 j^ h, or 6.
