I really need help on this quiz. A bedroom is 15 feet long and 12 feet wide. How much will it cost to carpet the room if carpet costs $8 p

15 * 12   * $ 8/ sq ft   =    $1440

Carpet is usually sold by the yd²      your question does not include units for the $ 8 per.......

IF it is square yards then     15/3 x12/3 = 5 x 4 = 20 sq yds       20 yd²  * $ 8/ yd² =  $ 160
