Question

A marble tiles measures 20 cm by 15 cm. How many tiles will be required to cover a wall of size 5 m by 3 m?

Answer 1

Answer:

500 tiles

Step-by-step explanation:

length of tile= 20 cm

breadth of height= 15 cm

Therefore, the area of the tile= length × breadth

= 20 × 15 cm²

= 300 cm²

Now, length of the wall= 5 m

breadth of the wall= 3 m

Therefore, area of the wall= length × breadth

= 5 × 3 m²

= 15 m²

Since 1 m= 100 cm

1 m²= 100 × 100= 10000 cm²

Therefore, area of wall in cm= 15 × 10000 cm²

= 150000 cm²

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

= 150000÷300

= 500

Answer= 500 tiles

Answer 2

Answer:

Answer:

500 tiles

Step-by-step explanation:

length of tile= 20 cm

breadth of height= 15 cm

Therefore, the area of the tile= length × breadth

= 20 × 15 cm²

= 300 cm²

Now, length of the wall= 5 m

breadth of the wall= 3 m

Therefore, area of the wall= length × breadth

= 5 × 3 m²

= 15 m²

Since 1 m= 100 cm

1 m²= 100 × 100= 10000 cm²

Therefore, area of wall in cm= 15 × 10000 cm²

= 150000 cm²

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

= 150000÷300

= 500

Answer= 500 tiles
