Answer 2

Answer:

800 tiles

Step-by-step explanation:

Length of rectangular region = 520 cm

Breadth of rectangular region = 140 cm

Therefore, Area of rectangular region = 520*140 = 72800 $cm^{2}$

Now,

Length of one tile = 13 cm

Breadth of one tile = 7 cm

Therefore, Area of one tile = 13*7 = 91 $cm^{2}$

So, Number of tiles needed = 72800 / 91 = 800 tiles
