Math question

Wait so what does 50% enlargement mean to you?

My point about 50% was that if the copier manufacturers want to allow arbitrary scaling they should've used "apply scale factor" instead of "enlarge", since enlarge 50% sounds silly if it halves the size.
 
Yes, I agree with you. If they wanted to indicate 400% of the old shape’s sides then they should’ve used scale factor of four. I’m sticking to what you and I previously agreed with. The wording is not good in the problem, and should be changed to scale factor. By enlargement of 400%,it refers to 5x the size (what I believe). Do you agree? Also, what does arbitrary scaling mean?

Without any context, I'd guess that it means 150% of the original size (half again as big).

Are you self-studying?

Kinda, I’m just doing some extra studying other than school. Also was kind of confused on the problem

I am not sure what it means. Enlarge by X% - add X%. Enlarge X% - ambiguous. In a face to face conversation I would've asked to clarify.
By arbitrary scaling I meant allowing scaling factor less than 100%, which means reducing in size.
 
Ok, so I did more research. I clicked the hint on the question and it said “What happens when a shape is enlarged by 400%? How many times bigger is it?” So I’m guessing it’s just poor writing. But if I were asked that question, I would also probably clarify.
