aider moi svpp !! cest a rendre pour demain matins

La croix suisse = 3/11 × 3/4 = 9/44 - 7/4 = 2/44 = 1/22

L'ovale = 1/3 × (1-2/3) = 1/3 × 1/3 = 1/9

Carré = 2/9 × (1/6 + 4/3) + (2/5 + 1/10 - 1/2) = 2/9 × 3/2 + (2/5 + 1/10 - 1/2) = 1/3 + 0 = 1/3

Triangle = 5% = 1/20

Parallélogramme = 4/3 × 1/20 = 4/60 = 1/15

Trapèze = 1 - (1 + 4/4,5) × 1/2 = 1 -(17/9 ) × 1/2 = 1 - 17/9 × 1/2 = 1 - 17/18 = 1/18

Hexagone = 17/75 + 2/3 × 4/25 - 2/15 = 17/75 + 8/75 = 25/75 = 5/15 - 2/15 = 3/15 = 1/5
