Area of square tiles = 16 ft²

Area of rectangular floor =  52 yards 40 yards =  2080 yards²


Number of square tiles needed = Area of Rectangular floor / Area of square tiles

 3feet = 1 yard

   Number  =        2080 yards² / 16 ft²

                 =      2080 (3 ft)² / 16 ft²             having substituted

                 =      2080 3² ft²  / 16 ft²

                  =    (2080 9) / 16

                   =   1170

So 1170 tiles are needed.
