a)
d1 = d2
d1 = 3[tex]\sqrt{5}[/tex] + 3[tex]\sqrt{5}[/tex] = 6[tex]\sqrt{5}[/tex]
P = 0.5 * 6[tex]\sqrt{5}[/tex] * 6[tex]\sqrt{5}[/tex] = 90 j^2
b)
D2 = 15 + 2 * 6 = 15 + 12 = 27 j
10^2 = 6^2 + h^2
100 = 36 + h^2
h ^2= 100 - 36 = 64
h = [tex]\sqrt{64}[/tex] = 8 j
P = 0.5 [(15 + 27) * 8] = 336/2 = 168 j^2

a.
Ob=4a
Ob=4•9=36
P=½•e•f
e=2•3V5=6V5
f²=9²-(3V5)²=81-45=36
f=V36=6
cała przekątna 2•6=12
P=½•12•6V5=36V5
b.
h²=10²-6²
h²=100-36
h²=64
h=V64
h=8
a=6+6+15=27
b=15
