And you thought that this was an easy answer.

So far we've got four answers:

131-134mm
135mm
141.42mm
150mm

Is SQR(100*200) actually correct?  Maybe, maybe not.  The SQR of
the two focal lengths does not assume a starting magnification
or angle-of-view.

<stir stir stir>

Maybe, we need to also look at magnification ratios.  Do does
FOV and magnification differ?  Does the millimeter
multiplication (50mm = 1:1, 100mm = 1:2, 200mm = 1:4) apply to
macro work, but the FOV apply for infinity?

Do toilets swirl in in clockwise directions in Australia?
