Looks like I need to revisit my maths text books :lol: I was adding 20% for waste on my earlier answer :smilewinkgrin:

Yes I forgot to allow for all the cuts.

For the type of triangle shown IBH went about it the right way due to it not being a right angled triangle. The full method would be to calculate using Herons Formula expressed as.

where

is the semiperimeter, or half of the triangle's perimeter.

However it's alot easier to go here and put the three lengths you have into the boxes and press calculate :8:

I always knew my degree in mathematics would come in handy one day!:lol:
Although the triangles area can be exactly determined, the number of tiles required will no doubt depend on the individual tile size and the amount of wastage due to pattern, shape, etc.
It would normally be easier with measurements of this size just to graph out the area and overlay your tile set out to calculate a reasonable gestimate!

So TJ, you couldn't really buy say 2.5m2 of tiles if the area was 2.5m2.
You would have to add 10% or more than likely add 20%+ to cover your wastage & would you charge the extra % onto the price for the customer??

Just buy 3 m2 FFs lol

You never got the humour within the post that was intended Charlie..

Id just measure it square , take away half and add 2 quarters

This is always an extremely delicate situation to confirm with any customer, and more so if the triangle although stated as being an isosceles is not of equal 60 degree angles!
As previously stated the size of the tile is often the determining factor with reference to wastage as the resultant cut off may not be able to be utilised in another position. I of course can fully cover a 2.5m areas perfectly with 2.5m of tiles - however it will resemble a mosaic in the style of Gaudi!
Therefore in the interest of clarity at the measuring stage I would assume the area to be a rectangle of the Pythagoras style and allow the tiles to overlap the Hypotenuse by full units, thus allowing a fairly accurate indication of actual tiles required.
If indeed a client was of the opinion that I'd over measured then I was obviously not meant to do their work in the first place.

Absolute Devine reply as always TJ.
