On a scale drawing 1/4 inch=1 foot. What are the dimensions on a Scale drawing of a room that is 20ft by 27ft

Gemiola [76]

Answer:

5 inches by $\frac{27}{4}$ inches

Step-by-step explanation:

According to the scale given, to convert "feet" to "inches", we have to multiply each feet by 1/4th. The drawing would be a "smaller" version of the original. That would be in inches.

So, 20 ft would be:

20 * 1/4 = 20/4 = 5 inches

and

27 feet would be:

27 * 1/4 = 27/4 inches

The dimension would thus be:

5 inches by $\frac{27}{4}$ inches
