Question

what number can you multiply each length in the scale drawing by to find the actual length? w = 2 in. l = 4 in. 1 in.: 3 ft

Explanation:

Step1: Recall scale - factor concept

The scale 1 in. : 3 ft means that 1 inch on the drawing represents 3 feet in actual length. The number we multiply by to convert from the drawing - length to the actual length is the scale - factor.

Step2: Identify the scale - factor

The scale is 1 in. : 3 ft, so the scale - factor is 3 (since for every 1 inch in the drawing, the actual length is 3 feet).
