Calculer la surface d'un espace

**membreV** · 21/01/2022, 09h49

Bonjour,
Je viens juste de d�buter en javascript.
Quand je lance mon projet, j'essaye de faire en sorte d'afficher automatiquement la surface de l'espace que j'ai pr�d�finis.
La surface doit apparaitre sur le plan 2d de ma pi�ce, donc dans la partie "construction du plan".

Malheureusement, apr�s avoir essayer beaucoup de bout de code, je n'arrive toujours pas � calculer la surface.
La surface devra etre calculer peut importe le nombre de cot�s de la pi�ce et leurs longueurs.

Avez-vous des id�es afin que ceci fonctionne ?

Dans certaines de mes tentatives, j'ai essayer de faire des conditions (si la pi�ce � 3 cot�s, 4 cot�s, etc.) ou encore j'ai essayer de prendre en compte chaque cot� de la pi�ce mais malheureusement rien de concluant.

Merci d'avance !

Voici le lien de mon projet stocker sur mega

d'apr�s ce que j'ai compris, vous devez d�couper les surface en triangles pour calculer l'air totale :
