Question

On a blueprint with a scale of 1 cm = 4ft, the length of the wall is 9 cm. If the scale of the blueprint were 1 cm = 3 ft, what would be the length of the wall? Plz show work and explain your work.

A. 12 cm
B. 13 cm
C. 15 cm
D. 18 cm

Answer 1

I'd say it's A because you multiply the 4 ft by 3 ft and you'll get 12 ft.
