Answer 1

Answer:

720 tiles are required .

Step-by-step explanation:

Breadth of floor = 4.5 m

Area of floor = Length \times Breadth = 3.6 \times 4.5=16.2 m^2

1 m = 100 cm

Length of square tile = 15 cm = 0.15 m

Area of square tile =Side^2 = 0.15^2=0.0225 m^2

No. of tiles required = \frac{16.2}{0.0225}=720

Hence 720 tiles are required .
