A room 5.44 m x 3.75 m is to be paved with square tiles. the least number of tiles required to cover the floor is?

Correct Answer: 176

Explanation:

Area of the room =(544 x 374) cm2
size of largest square tile = H.C.F. of 544 & 374
= 34 cm
Area of 1 tile = (34 x 34) cm2
∴ Least number of tiles required
= (544 x 374) / (34 x 34) = 176
