# Scaling Problem

Clara wanted to enlarge a figure on the photocopy machine. She set the enlargement factor to $$1.25$$. If the area of the figure was $$10$$ square inches before it was enlarged, what will the area be after it is run through the machine enlarged?

• Interesting question. Please, provide the context and doubts next time! – Quiet_waters Mar 7 '19 at 21:04

• So, enlargement factor always applies into the 'linear dimension' (sides in this case), I mean, how did you know that the enlargement factor did not apply to the area, that could becames directly $10\times 1.25$ ? Many thanks. – Quiet_waters Mar 4 '19 at 17:27
• More specifically, if I say: enlarge the figure by an $100\%$ enlargement, can a people answer if we should multiply the area by $2$, instead of the lenghts? If not, there is some paper or statement about it? Many thanks. – Quiet_waters Mar 7 '19 at 21:07
