Aires colorées

Tracez un rectangle dont les côtés sont parallèles aux lignes horizontales ou verticales du damier.
Les cases d'un damier sont alternativement noires (grises sur le schéma) ou blanches et la surface du rectangle se partage entre une partie noire et une partie blanche.

À quelle condition les aires des deux parties noires et blanches du rectangle sont-elles égales ?
