what is the least number of squares tiles required to pave the floor of a room 6 m 75 cm long and 4 m 5 cm broad ?
"length of largest tile = h . c . f . of 675 cm and 405 cm = 135 cm . area of each tile = ( 135 x 135 ) cm 2 . required number of tiles = 675 x 405 / ( 135 ^ 2 ) = 15 answer : a"
divide(rectangle_area(multiply(6, const_100), multiply(75, const_100)), square_area(add(multiply(const_4, const_10), const_1)))
