Question

In a scale drawing, the length of a rectangular room is 6 inches, and the width is 3 inches. The actual length of the room is 18 feet.

a. What is the scale of the drawing?


b. In a new scale drawing of the same room, the length of the room measures 4 inches. What is the scale of the new drawing? Explain.

Answer 1

For every 1 inch on the drawing, it's 3 feet in real life.

Explanation:

First, consider the length. The length is 6 inches on the drawing, while in actuality it is 18 feet. So every 6 inches represents 18 feet. Let's make a ratio; 6 : 18. To simplify it, divide both sides by 6; 6 : 18 = 1 : 3.
