No answer key was printed for this question.
Explanation
Area of the room $=(378 \times 525) \mathrm{cm}^{2}$. Size of largest square tile = H.C.F. of 378 cm and 525 cm = 21 cm. Area of 1 tile $=(21 \times 21) \mathrm{cm}^{2}$. ∴ Number of tiles required $=\left(\frac{378 \times 525}{21 \times 21}\right)=450$.
