i hope you can see answer

Answer 2

Step-by-step explanation:

Length of tile= 20 cm

breadth of height= 25 cm

Therefore, the area of the tile= length × breadth

= 20 × 25 cm²

= 500 cm²

Now, length of the wall= 5 m

breadth of the wall= 2 m

Therefore, area of the wall= length × breadth

5 × 2m²

= 10 m²

Since 1 m= 100 cm

1 m²= 100 × 100= 10000 cm²

Therefore, area of wall in cm= 10 × 10000 cm²

= 100000 cm²

Now, number of tiles= area of wall ÷ area of tiles

= 100000÷500

= 200
