1. o = 2*8cm + 2*3cm = 22cm
P = 8cm*2cm = 16cm²
2. o = 2*2cm + 2*7cm = 18 cm
P = 2cm*5cm = 10cm²
3. o = 40 cm+29cm+4cm+25cm = 98cm
P = 1/2 * (40cm+4cm) * 20cm = 440cm²
4. o = 10cm+4cm+5cm+7cm = 26cm
P = 1/2 * (10cm+7cm) * 4cm = 34cm²
5. o = 2*3cm + 2*8cm = 22cm
P = 3cm*8cm = 24cm²
Mam nadzieję że pomogłem i liczę na naj :>
