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 about: 360 $
