what is the least number of squares tiles required to pave the floor of a room 2 m 42 cm long and 1 m 76 cm broad ?
"length of largest tile = h . c . f . of 242 cm and 176 cm = 22 cm . area of each tile = ( 22 x 22 ) cm 2 . required number of tiles = 242 x 176 / ( 22 ^ 2 ) = 88 . answer : a"
divide(rectangle_area(multiply(2, const_100), multiply(42, const_100)), square_area(add(multiply(const_4, const_10), const_1)))
