Manday read that the arm of the Statue of Liberty is 42 ft long. She would like to know how long the Statue of Liberty’s nose is. How would you advise her to proceed?

Answer 1

Measure her own arm
measure her own nose

Liberty nose/Manday nose = liberty arm/Manday arm
or
liberty nose = liberty arm * manday nose/Manday arm

Answer 2

I'd advise her to check the measurements in this site.
