Question

what number can you multiply each length in the scale drawing by to find the actual length?
?
image of a rectangle with length labeled l = 4 in., width labeled w = 2 in., and a scale of 1 in. : 3 ft

Explanation:

Step1: Understand the scale

The scale given is \(1\) in. : \(3\) ft. This means that \(1\) inch on the scale drawing represents \(3\) feet in actual length.

Step2: Determine the multiplier

To find the actual length from the scale drawing length, we multiply the scale drawing length (in inches) by the number of feet per inch from the scale. Since \(1\) in. corresponds to \(3\) ft, the multiplier is \(3\) (when converting inches on the drawing to feet in actual, but more precisely, the scale factor is \(3\) ft per inch, so we multiply the drawing length by \(3\) to get actual length in feet).

Answer:

The number is \(3\) (where multiplying the scale - drawing length (in inches) by \(3\) gives the actual length in feet).
