Exercice 12 et 14 svp :) merci

Exercice 12:
On utilise le théorème de Pythagore:
FT^2 + FO^2 = TO^2
4.5^2 + 6^2 = TO^2
20.25 + 36 = TO^2
56.25 =TO^2
Racine de 56.25 = TO
7.5 = TO

Exercice 14:
On utilise le théorème de Pythagore:
GA^2 + AL^2 = GL^2
84^2 + 35^2 = GL^2
7056 + 1225 = GL^2
8281 = GL^2
Racine de 8281 = GL
91 = GL
