Answer:
40.5 feet
Step-by-step explanation:
It was given that the scale is 1 in. =3ft.
The perimeter of the blueprint measures 3.75 in. wide and 4.5 in. long.
The perimeter of the blueprint is
Perimeter =2(l+w)
We substitute the length and width to get:
Perimeter=2(3+3.75)
Perimeter=2(6.75)
Perimeter=13.5 in
To find the perimeter of the actual bedroom, we multiply by 3.
Perimeter of actual bedroom =3×13.5 ft=40.5ft
