Answer 1

Hi, Destiny,

    The question is in square inches, but the data is in feet.  You will need to convert the the length and width of the floor into inches.  Then find the number of square inches in the floor.  Divide that answer by 9, and you will have your answer.

 _______                               1 ft=12 in.                              15ft= 12*15=180 inches

|          |                               12 ft=  12 * 12= 144 inches

|          | 15 ft.= 180 inches

|          |    

⌊_____ |

       12 ft. = 144 in.                       Since we are talking about 9 in^{2 ,  then we need to find the area of the rectangle.}

                                                    A= L*W=  180*144=__________  I hope this helps!    Susan C.
