According to the PYTHAGORAS THEOREM

              H² = B² + P²

          => 10² = 6² + P²

         => 100 = 36 + P²

         => P² = 100 - 36

            => P² = 64

           => P = √64

           => P = 8cm

Area of triangular tile = 1  X  base X height

                                         2

                                => 1 X 8 X 6

                                     2

                                    => 4 X 6

                                   => 24cm²

1m² = (100 x 100)cm²

        => 10000cm²

1296m² = 1296 X 10000

             => 12960000cm²

Area of floor = 12960000cm²

Area of triangular tile = 24cm²

No. of tiles required = 12960000

                                           24

                     => 540000 tiles
