Szczegółowe wyjaśnienie:
a) a = 4cm h = 2cm P = 4cm * 2cm/2 = 4cm2
b) a = 5cm h = 4cm P = 5cm * 4cm/2 = 10cm2
c) a = 10mm - 1cm h = 2cm P = 1cm * 2cm/2 = 1cm2
d) a = 40mm - 4cm h = 4cm P = 4cm * 4cm/2 = 8cm2
e) a = 2m - 200cm h = 3cm P = 200cm * 3cm/2 = 300cm2
f) a = 3dm - 30cm h = 2cm P =30cm * 2cm/2 = 30cm2
