a room 4 m 47 cm long and 7 m 77 cm broad is to be paved with square tiles . find the least number of square tiles required to cover the floor .
"explanation : area of the room = ( 447 x 777 ) cm 2 . size of largest square tile = h . c . f . of 447 cm and 777 cm = 3 cm . area of 1 tile = ( 3 x 3 ) cm 2 . number of tiles required = ( 447 × 777 ) / ( 3 × 3 ) = 38591 answer : option d"
divide(multiply(add(multiply(4, const_100), 47), add(multiply(7, const_100), 77)), multiply(subtract(47, add(multiply(const_2, const_4), const_2)), subtract(47, add(multiply(const_2, const_4), const_2))))
