Given that :- rectangular bedroom dimensions= 2.25 inches by 2.5 inches means length=2.25 inches and breath=2.5 inches

according to the question, 1/8 inches=1 foot

then 2.25 inches= 2.25/ 1/8 foot

Friction in denominator is reciprocal when we goes to numerator and multiplied by numerator digit

2.25*8/1=2.25*8

                =18 foot

similarly, 2.5 inches=2.5/ 1/8 foot

                                      =2.5* 8/1

                                      =2.5*8

                                        =20 foot

now length of rectangular room = 18 foot and breath= 20 foot

now, area of rectangular room = length*breath

                                                      =18*20 

                                                      =360 square feet

so, the actual area of rectangular bedroom is 360 sq. ft.
