A simple maths problem
Hi,
I have the following maths question with options given. Can someone help me in finding what is the answer and how it is calculated
Mr Chan's garden is 40 m long and 25.5 m wide. If he paves the garden with tiles which are 50 cm square, how many tiles he need
a) 4080
b) 1000
c) 408
d) 2000
e) 2020
Thanks

Re: A simple maths problem
Think about how many he can fit along each side.
40m long - each tile 50cm - so ....
Try and think it through and if you can't work it out we'll give another hint.

Re: A simple maths problem
Doesn't 50 cm square mean that area of each tile is 50 cm square? Isn't the question a bit vague as the kid has to assume that 50 is the length of one side and not the area of a whole tile?
Thanks.
Thanks.
Re: A simple maths problem
The wording means that the tile is 50 cm along each side and that it is a square.

Re: A simple maths problem
thanks for replying. I got the context.
Re: A simple maths problem
You are probably thinking of '50 square centimetres'? Which would be a tile with sides of a length just over 7cm.
