Good morning virtual pupils, here is today's problem. No I don't mean those troublemakers, Gilly and Doodle! 
.
Many years ago, I had to lie flat for a couple of hours, whilst having a full body scan done. I passed the time, counting how many squares were on the ceiling. ?
The difficulty is that four square ceiling tiles together make one large square, so I kept losing count. The radiographer thought I was mad.
That was a hint to the solution, by the way.
Oops, that title didn't quite come out right! 
I was panicking, for a moment I thought I had forgotten to write down the answer! 
Oh, you are all so confident! ?
Granny Gravy, answers, but no explanations. .
Back to the drawing board, all of you.
Remember the properties of a square: all sides are equal.
There are squares within squares.
