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?

Respuesta :

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.
