A square has four equal sides
Inside nothing hides
Unlike a cube it is quite flat
Like the rug on which the cat sat
Its surface area is a square root
Quite dull, not a hoot
Take one side and multiply it by the same
Yes, quite dull still, what a shame
So if the side is 4cm long
I know, this is not much of a song
Multiply 4 by 4
You will get the surface area, I know what a bore!
4 times 4 is 16
It’s true I’m not being mean
So you end up with 16 little squares
No I’m not putting on airs!!
The final measurement is 16 cm²
Just so you know, in case you cared
It is A = a² whatever size the square
Try it yourself, if you dare!
