Answer:

50 tiles

Step-by-step explanation:

The area of a square is the square of the side. The area of each tile is

a = (20 cm)^2 = 20 cm * 20 cm = 400 cm^2

Now we convert 2 square meters into square centimeters.

2 m^2 * (100 cm)/m * (100 cm)/m = 20,000 cm^2

2 m^2 = 20,000 cm^2

Now we divide the total area by the area of one tile.

(20,000 cm^2)/(400 cm^2) = 50

Answer: 50 tiles
