Your post asks "which of the following", but does not provide what should follow.

So, I qualify your post as self-contradictory with the intention to deceive a reader,
and recommend you to throw it to the closest garbage bin as soon as you can, i.e. immediately.

Do not post this kind of messages to this forum.

The shape is a square so length and width are the same size.
d for the diagonal length, d=38.
x%5E2%2Bx%5E2=d%5E2
2x%5E2=d%5E2
2x%5E2=38%5E2
x%5E2=%2838%2F2%29%2838%29
x%5E2=19%2A38
x%5E2=2%2A19%2A19
highlight%28x=19%2Asqrt%282%29%29

"the following,..." for choices of answers was not shown. They must include 19sqrt%282%29, which is the
choice needing to be picked.
