We show that, among the projective planes embedded into the real projective space RP3 endowed with the Berger metric, those of least area are exactly the ones obtained by projection of the equatorial spheres of S3. This result generalizes a classical result for the projective spaces with the standard metric.

On démontre que, parmi les plans projectifs dans l'espace projectif réel RP3, muni de la métrique de Berger, ceux qui réalisent le minimum de l'aire sont exactement ceux qu'on obtient par la projection des sphères équatoriales de S3. Le résultat généralise un résultat classique pour l'espace projectif muni de la métrique ordinaire.
