Question

The floor of the restaurant is a square of sides 28m. The floor is covered with square tiles of sides 40m. Calculate the total number of tiles used.​

Answer 1

196000 tiles.

Explanation:

The 28 m is 2800 cm. So a 28 x 28 meter square would be 2800 x 2800 centimeter square.

The tiles are 40 cm.

If you divide 40 from (2800 x 2800). (2800 x 2800) ÷40 = 196000

So 196000 tiles.

I'm not entirely sure if that's correct, but if it helps that's awesome.
