what is the least number of squares tiles required to pave the floor of a room 8 m 82 cm long and 2 m 52 cm broad ?
"length of largest tile = h . c . f . of 882 cm and 252 cm = 126 cm . area of each tile = ( 126 x 126 ) cm 2 . required number of tiles = 882 x 252 / ( 126 ^ 2 ) = 14 . answer : a"
divide(rectangle_area(multiply(8, const_100), multiply(82, const_100)), square_area(add(multiply(const_4, const_10), const_1)))
