a room 5.44 m long and 3.74 m broad is to be paved with square tiles . the least number of square tiles required to cover the floor is :
area of the room = 544 * 374 sq . cm size of largest square tile = hcf of 544 cm & 374 cm area of 1 tile = 34 * 34 sq . cm therefore , number of tiles = ( 544 * 374 / 34 * 34 ) = 176 answer : a
divide(multiply(multiply(5.44, const_100), multiply(3.74, const_100)), multiply(add(add(add(const_10, const_10), const_10), const_4), add(add(add(const_10, const_10), const_10), const_4)))
