converting feet into units

Question

a game room has a floor that is 225 feet by 30 feet. a scale drawing of the floor on grid paper uses a scale of 2 unit 5 feet. what are the dimensions of the scale?

Answer 1

game room has a floor that is 225 feet by 30 feet.

 

scale : 2 unit for 5 feet -> 1 unit for 2.5 feet

 

so for 225 feet = 225/2.5 = 90 unit

 

          30 feet = 30/2.5 = 12 unit

 

dimension on scale = 90 unit by 12 unit
