Question

If a sheet of paper measures 8 in. wide by 8 in. tall and is folded along the diagonal, how long is the fold?

Answer 1

The answer is 11.31 in.

Answer 2

Since both sides are 8 inches, I'm assuming that it's a square.

the diagonal is √2 * side, so the fold is 8√2.

i hope this helps :)
