Bonsoir j'ai encore un problème de maths et c'est un devoir maison pour demain... C'est l'exercice N•2 que je ne comprends pas.
Pourriez-vous m'aider?

Bonjour,
A = (2/3*7/5)+(7/3)²
à calculer = 287/45 je te laisse chercher les calculs

Bonjour
aire de la figure = ( 7/3)² + ( 2/3 x 7/5)
= 49/9 + 14/15 = 2205/45 + 42/45 = 2247/45 =
749/15
