help pls and explain step by step on how to solve it cuz i have to show work, i found an answer but it doesn't make sense (picture and word problem are in the picture)

108 inches.

Step-by-step explanation:

Since a square has 4 sides, I divided 36 inches by 4, which equals 9 inches for each side. However, this is only a 1/12 scale so you have to multiply 9 times 12 to get 108 inches. Please correct me if I am wrong because everybody makes mistakes sometimes. I hope this was helpful to you.          

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

answer: x=60
