what is the least number of square tiles required to pave the floor of a room 50 m 00 cm long and 11 m 25 cm broad ?
solution length of largest tile = h . c . f . of 5000 cm & 1125 cm = 25 cm . area of each tile = ( 25 x 25 ) cm 2 ∴ required number of tiles = [ 5000 x 1125 / 25 x 25 ] = 9000 . answer d
divide(multiply(add(multiply(11, const_100), 25), multiply(50, const_100)), power(25, const_2))
