Import picture - calculate, geometry & graphing

[tjurij]

I plan to buy it but I would like to know beforehand if it enables certain functions.
I intend to perform area calculations from real-word images, mainly with a polygon (aerodynamics for cars, cyclist - ofcourse not scientific, ).
The video example from the previous post does this accurately enough for my needs (Tasmania area).
If it's possible to do something like that with the HP Prime, then there's no stopping me from buying it.
Can you maybe chek is this will work in Prime?
Thx
