Help with using binomial theory to calculate error

How can you form a square with 17 square tiles?

MUST it not be 6/16 = .375 = area of each of 16 square tiles?

The +- 2% doesn't make much sense...
Denis,
Crumble up the the 17th tile and fill in the gaps. No one said you had to use all of the tiles as they stood.
 
I'm too cheap to crumble anything, and it'll take a lot more than that to convince me, Ishuda ;)

A customer requires a square patio with area of exactly 6m^2.
Slabs of area .36 m^2 were erroneously calculated as being required.
This makes it obvious that 16 slabs were intended.
6 / 16 = .375.
.36 / .375 = .96, so 4% short.
The original problem strangely asks "what are your conclusions";
mine is "not 2%, but 4%".

I turn that in as answer to that strange problem and I expect 100% :rolleyes:

Each side of the square is 2% short - making the area 4% short
