1.	3. A marble tile measures 20 cm by 15 cm. How many tiles will be required to covere a wall of size Smb3m?
Answer» Length of tile= 20 cmbreadth of height= 15 cm Therefore, the area of the tile= length ×breadth = 20 ×15 cm²= 300 cm² Now, length of the wall= 5 mbreadth of the wall= 3 m Therefore, area of the wall= length ×breadth5 ×3 m²= 15 m² Since 1 m= 100 cm1 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 thanks

Answer»

Length of tile= 20 cmbreadth of height= 15 cm

Therefore, the area of the tile= length ×breadth

= 20 ×15 cm²= 300 cm²

Now, length of the wall= 5 mbreadth of the wall= 3 m

Therefore, area of the wall= length ×breadth5 ×3 m²= 15 m²

Since 1 m= 100 cm1 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
