I usually don't deal with heavy maths on a regular basis so the way I communicate this may not be spot on, but here goes.
I wish to create shapes of ANY number of sides that have a specific area and I know the area of which they have to be.
For example, the area is 9cm squared, so to create a square shape from that I would squareroot it to find the length and breadth in order to draw the shape. I can also manage to do the same for a triangle by reversing (1/2(bxh)), but the shapes I want to draw are:
Semicircle - (I think i can do this one)
Heptagon - 7sides
dodecagon - 12 sides
hexadecagon - 16sides
icosagon - 20 sides
Any ideas how I create these shapes that have specific areas?
Thanks very much in advance,
