What is in this set

The numbers in this set run from 2 to 20.
Every problem in it will need the length factor used twice, because the units are square ones.
A careful solution takes 2 written steps on average.
The mistake this set invites most often, in 100% of the problems: 100 is the factor between the lengths.
Answers are a whole number.

Drawing 240 problems from this page produced 38 different ones, 16% — so a sheet of 20 will come back to a problem you have seen — there are only so many sensible ones of this kind.
