Answer 2

Answer:

625 tiles

Step-by-step explanation:

Side= 12 cm

In m = 0.12 m

Area of square =

$side \times side \\ = 0.12 \times 0.12 \\ = 0.0144 \:{ m}^{2}$

Side of floor = 3m

Area of floor =

$side \: \times \: side \\ = 3 \times 3 \\ = 9 \: {m}^{2}$

No. of tiles =

$\frac{9}{0.0144} = \frac{9 \times 10000}{144} \\ = \frac{10000}{16} \\ = \frac{2500}{4} \\ = 625 \: tiles$
