Question

The side of a square tile is $10cm$. How many tiles can be fixed on one side of a wall which is $2.5$ m long and $2$ m high?

• A. $100$
• B. $400$
• C. $5000$
• D. $500$

Answer 1

Answer: (D)

$500$

Area of the wall = $250\times 200=50,000$ sq cm
Area of the tile = $10\times 10=100$ sq cm
Number of tiles required = $\frac{areaofthewall}{areaofthetile}$
=$\frac{50000}{100}$
