A blueprint for a house has a scale of 1:20. A wall in the blueprint is 10 in. What is the length of the actual wall. A) 16.67 B)200 Feet C) 16.67 D) 2400 feet Please show your work or explain.

OpenStudy (espex):

You have a scale of 1:20, so for every 1 on the print you multiply by 20 for the real world. \[\frac{1}{20}=\frac{10}{x}\] and solve for x. Recall that this is in inches and the question is asking for an answer in feet.
