bonsoir,
AB = ( 10 - 2 )² + ( 2 + 2 )² = 8² + 4 ² = 64 + 16 = 80
AM = ( 8 - 2 )² + ( 6 + 2 )² = 6² + 8 ² = 36 + 64 = 100
BN = ( 0 - 10 )² + ( 2 - 2 )² = ( - 10 )² = 100
MN = ( 0 - 8 ) ² + ( 2 - 6 )² = ( - 8 )² + ( - 4 )² = 64 + 16 = 80
ABMN est un parallélogramme rectangle
aire = 80 x 100 = 8000
tu fais pareil pour le second exo
