Chuanxi planned a rectangular sidewalk with a length of 21 ft. He made a scale drawing using a scale factor of 1 in. = 7 ft. He
decided to change the length of the actual sidewalk to 27 ft. If the scale drawing still has a length of 3 in., what does 1 in. represent in the new scale?
The coordinated of A would be 1,1. Instead of going through the trouble of mentally moving the entire thing, just focus on the one you need to know the answer to, aka A.
