Shaklning perimetri qanday hisoblanadi?

Shaklning perimetrini topish uchun shaklning barcha tomonlari uzunliklarini qoʻshamiz.

1-misol:

Trapetsiyaning perimetri nechaga teng?

10\,\text{m}10m10\,\text{m}10m8\,\text{m}8m18\,\text{m}18m

Perimetrni barcha tomonlarning uzunliklarini qoʻshish orqali topishimiz mumkin.
