I think I must be retarded or something as I can't remember how to work out the answers to some simple mathemtic problems. I used to be able to do these as a kid

Here's an example:

One carpet tile measures 50cm by 50cm. How many tiles are required to cover a floor which measures 5m by 4m? = 80

I just can't remember how to do it!

PeteBrant

500X400= 200,000cm2

Tile = 50X50=2,500cm2

20,000 / 2,500 = 80 tiles

so yeah, you were right

little-ginge

well you see, SW..
1+1=2
2+1=3
3+1=4

and so on

I can't either, I still use yards feet and inches and I've got a converter on my phone as well.

Or, 2 tiles do 1 metre so you'd get 10 tiles along the 5m edge, 8 down the 4m edge...10 x 8 = 80

ScoobyWon't

I can do that

And even subtractions too

Ah, it makes sense now...

So, seeing if I've grasped it, if I have a garden measuring 12m by 9m with a rose bed in the centre measuring 3m by 6m to work out the total non-rose area I would do:
12x9 = 108
3x6 = 18.

108 - 18 = 90

Ah but can you tie your shoelaces by yourself??

ScoobyWon't

Tie? I've got velcro

The important thing is that I can work out your speed minus the speed limit and then ticket your ****

Are you a cop SW?

ScoobyWon't

Me, a cop?

No.

I was expecting a Triganometry question or something, seems a bit simple to me this one Logic if you like

little-ginge

SW as a rasher of bacon? nw that would be plain stoopid

ScoobyWon't

I did say the question was bloody easy!

ScoobyWon't

I haven't forgotten about your shopping list

little-ginge

I might need to add to that if my neighbours start a creche a stun gun would be handy and some tear gas for when they riot at snacktime

Already answered but my simpleton take on it

5x4m = 20 square metres

4 tiles needed per square metre.

4x20=80 Tiles

Do what I would do, buy one box of tiles at a time lay them, keep buying single boxs untill you're done, then simply count them.

just buy one tile and then draw around it. move it along and repeat until area is covered in squares.

then count the squares....
its cheaper and less visits to the DIY store

Dammit that could have saved me hours

WRX_Dazza

infact you count paint the squares and avoid buying the tiles !!! lol

Cover your floor in old newspapers, sellotape them all together. Then, take your new patern to the DIY and lay the tiles out on it till you have enough
