Answer:
I can give you the perimeter "algorithm" but not the flowchart.
Here you go:
p = w * 4
p = perimiter,
w = width/height
4 = the amount of sides needed.
perimeter = width * 4
to include both width and height, we would instead use:
perimeter = 2(width+height)
This also works with rectangles ^
--------------------------------------------------------------------------
To find an area, it is just width * height. This is also compatible with rectangles.
