Here is how you would set it up...
You would to 12/100 = x/2 and cross multiply and solve by division. I believe. I'm almost positive that's how you do it. If that don't work out, comment and I'll respond.

Hey there! :)
Answer:
x = 242 mm.
Step-by-step explanation:
Begin by setting up a proportion between the actual college building and the drawing.

Cross multiply:
99 × 22 = 9 × x
2178 = 9x
Divide both sides by 9:
2178/9 = 9x/9
x = 242 mm.
