Answer:

817

Step-by-step explanation:

15.17 m = 1517 cm

9.02 m   =  902 cm

take HCF 1517, 902 = 41  ↓

902)1517(1

        902

        615)902(1

               615  

                287)615(1

                       287  

                       328)287(1

                              328

                                  41}328(8

                                       328

                                          0

  = Area of Room / area of tiles

  = L * b / a*a

  = 1517*902 / 41*41

  = 37*22

  = 814
