Question

The dimensions of an office conference room are 10 feet by 18 feet. If the conference room blueprint dimensions are 5 centimeters by 9 centimeters, what is the scale of the blueprint?

Answer 1

10<18
5<9

10ft/5cm or 2ft:1cm

5cm/10ft = 1cm/2ft
1cm on the blueprint is the same as 2 feet of the actual conference room.
