Further thoughts about what squares and triangles tell us.
Each Case below gives a shape. Beside each shape write an equation for the area as
"A = ..." and perimeter as "P = ..." Use the notations given.

This continues the previous "I". Leads, along a meaningful path, to valuable geometry. You can use this however you choose. Think about this plan ~ how to do it with your text. All what I have for your needs needs clean-up only. (which I am doing anyway).
1) Symmetry does the area. Pythagoras does the perimeter. Mimi... you look up shape. Shape is an "abstraction". So what then is an abstraction?
2) The area is symetrically 1/2 by symettry of (L xL) minus ... whole is sum of parts...
3) Here is some "symmetry" for area. And some Pythagoras.
