Final answer:
Without additional information, we cannot determine the scale being used in the model scale drawing of the bedroom. The scale factor corresponds to the ratio between the measurements on the model and the actual measurements.
Step-by-step explanation:
We cannot determine which scale is being used for the model scale drawing of the bedroom since crucial information is missing from the question. Typically, determining the scale factor of a model requires knowing either the actual dimensions and the dimensions on the model or the intended scale.
For example, if the actual bedroom measures 12 feet by 12 feet and the drawing shows the bedroom as 6 inches by 6 inches, then the scale would be 1/2 inch = 1 foot, because every half inch on the drawing represents one foot of actual space. To illustrate, you would set up a proportion comparing the model dimension with the real dimension.
If the real bedroom measures 12 feet (144 inches) in width, and the corresponding width on the drawing is 6 inches, then you would use the scale factor formula which is:
scale drawing measurement / actual measurement = scale factor
6 inches / 144 inches = 1/24, which can be interpreted as 1/2 inch = 1 foot when considering typical scales used in drawings.
