h=3,6cm und q=2,7cm
p*q = h^2 | Höhensatz
p = h^2 / q = 3.6^2 / 2.7 = 4.8
p = 4.8 cm
c = p+q= 4.8 + 2.7 = 7.5
c = 7.5 cm
Fläche
A = (c * h)/2 = (7.5 * 3.6)/2 = 13.5
A = 13.5 cm^2
b^2 = h^2 + q^2
b = √(3.6^2 + 2.7^2) = 4.5
b = 4.5 cm
a = √(3.6^4 + 4.8^2) = 6
a = 6 cm
u = a + b + c = 7.5 + 6 + 4.5 = 18
u = 18 cm
