328 square feet.
Step-by-step explanation:
Julie is constructing a scale model of her room.
The model of the rectangular room is
inches by 8 inches.
The scale factor of the model is 1 inch = 2 feet.
The actual length of the room =
× 2
=
× 2
=
=
feet
= 20.5 feet
The actual width of the room = 8 × 2
= 16 feet.
The actual size of the room is 20.5 feet by 16 feet.
Area = Length × width
Area of the room = 20.5 × 16
= 328 feet²
actual area 328 square feet and scale factor is 1 inch = 2 feet.
