A scale drawing shows a room to be 3 inches by 4-1/2 inches. carpet, which is $15 per square yard, is to be installed in the room. if the scale is 1 inch to 4 feet, how m4uch would it cost to install the carpet?

The first thing we must do for this case is to look for the real dimensions.

We have then:

(3) * (4) = 12 feet

(4-1 / 2) * (4) = 18 feet

We are now looking for the room area:

(12) * (18) = 216 feet ^ 2

We consider the following conversion:

1 yard = 3 feet

Applying the conversion:

(216) * (1/3) ^ 2 = 24 yd ^ 2

The total cost will then be:

(24) * (15) = 360 $

Answer:

it would cost to install the carpet а bout:

360 $
