@Saisrivarsha P looks tricky but we can simplify it down ,first, we find the actual total distance of the facility by A = 36 * 120, Next, we calculate the final side length of the third model after the changes by typing L = 36 * 1.25 * 0.9. To find the new scale, we set up a relationship with L * d1 ~ A. This gives us a d1 value of around 106.67 . Since we need to round to the nearest integer, the final answer is 107
