Answer 1

the most difficult qn!!

Answer 2

You can google them

Answer 3

I look at questions in one of two ways: easy if I can answer it, and hard if I cannot. Because of that mindset, I never deride the questions of others.

The answers are google-a-ble. Two of the formulas are essentially the same and the third can be remembered by drawing one diagonal on one of the first two polygons mentioned.

@Toyjia Go to Google and enter the following in the search box :"purple math" area formulas}. The second listing should be "Geometry Formula Review."
