Question

Square tiles of side 30 cm were

used to cover a floor which is 9 m
long and 6 m wide. How many
square tiles were used?​

Answer 1

The answer would be 600 I think

If 1 meter= 100 cm then you would convert 9 and 6 to 900 and 600. Then if each tile is 30 centimeters then you would do 900/30= 30 and 600/30= 20. Then to find the amount for the whole area you have to do 20 x 30= 600.

I hope this helps :)
