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?

1ft=.33in

Step-by-step explanation:

For every 1ft in the room its .33 on paper.

.33333333333333333333333333333x18=6

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

Step-by-step 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.

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

1/3 + 1/5 = 8/15.
