There's no reason this shouldn't be written as "a square whose sides equal 1". I've never seen a single practice test from any other company that uses the phrase unit square

Hi Isaac,

'Unit square' is a standard and frequently used term in basic mathematics. It could appear on the test.

Isaac, thanks for the feedback. As the app developer, we will relay the feedback to the author. On the bright side at least you learned a new vocab.
