Question

TWENTY POINTS.
Suppose that one doll house uses the 1 inch scale, meaning that 1 inch on the doll house corresponds to 1/2 foot for life-sized objects. If the doll house is 108 inches wide, what is the width of the full-sized house that it's modeled after?
In inches and feet

Answer 1

Answer: 54 feet or 648 inches.

Step-by-step explanation:

1. You know that 1 inch on the doll house corresponds to 1/2 foot for life-sized objects. Therefore, you can calculate the width of the full-sized house that it's modeled after, as following:

$width=\frac{108in*1/2ft}{1in}\\width=54ft$

2. Then, the width in feet is: 54 feet.

3. And the width in inches is:

(Keeping on mind that 1 feet=12 inches)

$\frac{54ft*12in}{1ft}=648in$
