There is no formula as such. You partition the compound shape into simpler shapes whose areas you can work out using formulae, and then add all those parts together.

There are different formulae for different plane figures. Since there are infinitely many possible shapes there are infinitely many formulae.
what kind of measurement to use when finding the area of a 2d shape
It depends on the shape. There are different formulae for different shapes.
The answer will depend on the shape that the circle is embedded in! There are different formulae for different shapes.

There are different formulae for different shapes.
It depends on what the shape is and what information you have about it. There are many different formulae.

what kind of measurement to use when finding the area of a 2d shape
You work both out from measurements of the shape and the relevant formulae.
It depends on the shape. There are different formulae for different shapes.
The answer will depend on the shape that the circle is embedded in! There are different formulae for different shapes.
The formula will depend on the shape whose area you wish to find. There are different formulae for some simple shapes.
It depends on the shape of the area you need to calculate. There are formulae for given shapes but not necessarily for irregular ones
L.A.= 2*pi*radius*height its not like finding the area of a rectangle. a cylinder is a 3-D shape and a rectangle is a flat shape
