Odpowiedź:
P= [tex]\frac{1}{2}[/tex] * a * h
P = [tex]20 cm^{2}[/tex]
a * h = [tex]40 cm^{2}[/tex]
a = 10 cm
h = 4 cm
a = 4 cm
h = 10 cm
a = 5 cm
h = 8 cm
a = 8 cm
h = 5 cm
a = 20 cm
h = 2 cm
a = 2 cm
h = 20 cm
Odp : Wymiary kilku takich trójkątów to : a=10 cm i h=4 cm , a=4 cm i 10 cm , a=5 cm i h=8 cm , a=8 cm i h=5 cm , a=20 cm i h=2 cm , a=2 cm i h=20 cm .
