what is the least number of squares tiles required to pave the floor of a room 15 m 17 cm long and 9 m 2 cm broad
"explanation : length of largest tile = h . c . f . of 1517 cm and 902 cm = 41 cm . area of each tile = ( 41 x 41 ) cm ^ 2 . required number of tiles = ( 1517 x 902 / 41 * 41 ) = 814 . answer : a"
divide(rectangle_area(multiply(15, const_100), multiply(17, const_100)), square_area(add(multiply(const_4, const_10), const_1)))
