An architectural drawing lists the scale as 1/4" = 1'. If a bedroom measures 1.5" by 2.25" on the drawing, how large is the bedroom?

Given that the house representation is given by 1/44"=1', then the house who dimension is 1.5" by 2.25" has an actual length of:

(2.25) / (1/4) * 1

=2.25*4

=9'

and actual width of:

(1.5) / (1/4) * 1

=1.5*4

=6'

therefore the size of the room will be:

Area=length*width

=9*6

=36 square inches
