Answer: A
Explanation: You need to find the dimensions of the scale model of the lot that can be multiplied equally to get the original length. Basically 40 m and 100 m need to be divided by the same number to make the scale model evenly, and right off the bat you see that 10 and 25 could be multiplied by 4 and equal the original numbers. Hope this helps! Also sorry if it was kinda hard to understand lol, when i explain things its hard to get out of my own head ;P
