surfarea ([[x,y],[x,y],[x,y],[x,y]])

surfarea ([[x,y],[x,y],[x,y],[x,y]]) → number

It produces the resulting area formed by points entered sequentially, which together define a closed plane.

Example:

<br><O N="surfareaObject1" T="Project" Category="Functions" TransAlignRule="1"><br> <!-- created by ParamML Examples on 8/24/2023 --><br> <P N="area" V="surfarea([[0,2],[2,2],[2,0],[0,0]])" /><br></O><br>
