3. A rectangular room is 15 feet by 9 feet. Carpet costs $3.50 per square foot. How much would it cost to buy carpet to cover the floor?

Answer The dimensions of the room in inches on the scale drawing is inches by inches OR 3.25 inches by 3.75 inches

Step-by-step explanation:

From the question, the dimension of the room is 13feet by 15feet.

Now, if the room is drawn to 1/4 inch represents 1 foot scale, i.e 0.25 inch represents 1 foot, then the dimension of the room in inches on the scale drawing can be determined as follows

Since 1 foot = 0.25 inch  

∴ 13 feet on the scale drawing will be 13 × 0.25 = 3.25 or 3 1/4 inches

and 15 feet on the scale drawing will be 15 × 0.25 = 3.75 or 3 3/4 inches

Hence, the dimensions of the room in inches on the scale drawing is

inches by inches OR 3.25 inches by 3.75 inches.
