Question

How many tiles whose length and breadth are 12 cm and 5 cm respectively will be required to fit in a rectangular floor whose length and breadth are 10 m and 6 m respectively?



Ans????​

Answer 1

Area of one tile = 12×5 = 60cm²

And the Area of Rectangular floor = 10×6 = 60m²

Now, as we know that : 1 m = 100 cm

=> 1 m² = 10000 cm²

=> 1 cm² = 1/10000 m²

=> 60 cm² = 60/10000 m²

Now, let x tiles will be required to fit in floor

Then, according to the question :

$\frac{60}{10000} \times x = 60 \\ \\ = > x = \frac{60 \times 10000}{60} = 10000$

So, 10000 tiles will be required ✔️
