what is the least number of squares tiles required to pave the floor of a room 2 m 25 cm long and 1 m 35 cm broad ?
"length of largest tile = h . c . f . of 225 cm and 135 cm = 45 cm . area of each tile = ( 45 x 45 ) cm 2 . required number of tiles = 225 x 135 / ( 45 ^ 2 ) = 15 . answer : a"
divide(rectangle_area(multiply(2, const_100), multiply(25, const_100)), square_area(add(multiply(const_4, const_10), const_1)))
