The floor plan of a house is drawn to the scale of 1/4 in. = 1 ft. the master bedroom measures 3 in. by 3 3/4 in. on the blueprints. what is the actual size of the room? explain your reasoning

3 in = (3 in)/(1/4 in)
       = (3)(4)
       = 12 ft

3 3/4 in = (3 3/4 in)/(1/4 in)
             = (15/4 in)(1/4 in)
             = (15)(1)
             = 15 ft

Therefore, the actual size of the room is 12 ft x 15 ft = 180 square ft

I think you can handle the reasoning. :D
             

2/1 or just 2. sorry if i get this wrong
