Question

I don't understand what question b) i) is asking me to do?

What does tiles needed to fit across the length mean?

btw, the bathroom is 8m long and 7m wide

​

Answer 1

32

Explanation:

Imagine someone is trying to put tiles on a bathroom floor - this is the situation in this question. "tiles needed to fit across the length" is asking how many 25cm tiles can fit in the length of the bathroom, which is 8m.

To do this, we need to do some conversion.

8m to cm = 800cm

800 ÷ 25 = 32

This means 32 tiles are needed to fit across the length of the bathroom floor.
