Sapna is standing on a rectangular floor with a breadth of 50 m. She decides to get it covered with marble tiles. How many tiles would be required to cover the floor area of 45000 sq. m, if each tile measures 50 m x 5 m?

Length of the tile = 50 m Breadth of the tile = 5 m Area of each tile = Length x breadth             =>50 m x 5 m             =250 sq. m Area to be covered = 45000 sq. m Number tiles of required = Area to be covered /Area of each marble tile                                              = 45000/250                                              = 180 tiles
