Please draw me 18 perimeter ahlukahlukene

Ukuze uzobe iidayagramu ezahlukene ezinomjikelezo wamayunithi ayi-18, kufuneka uqale ufumane ubude nobubanzi obudibanisa ukuze bube yi-9. Oku kungenxa yokuba ifomula yomjikelezo werhombhoyi (rectangle) ngu $P = 2(l+w)$. Ukuba $P = 18$, ke:

$$18 = 2(l+w)$$

Sahlula ngo-2 kumacala omabini:

$$9 = l+w$$

Ngoku, nanga amanye amadayagramu erhombhoyi onokuwazoba kwigridi yakho, usebenzisa isikwere ngasinye njengeyunithi enye:

• Idayagramu 1:

  • Ubude: 8 iiyunithi
  • Ububanzi: 1 iyunithi
  • Umjikelezo: $2(8+1) = 2(9) = \text{18 iiyunithi}$

• Idayagramu 2:

  • Ubude: 7 iiyunithi
  • Ububanzi: 2 iiyunithi
  • Umjikelezo: $2(7+2) = 2(9) = \text{18 iiyunithi}$

• Idayagramu 3:

  • Ubude: 6 iiyunithi
  • Ububanzi: 3 iiyunithi
  • Umjikelezo: $2(6+3) = 2(9) = \text{18 iiyunithi}$

• Idayagramu 4:

  • Ubude: 5 iiyunithi
  • Ububanzi: 4 iiyunithi
  • Umjikelezo: $2(5+4) = 2(9) = \text{18 iiyunithi}$

Zoba ezi rectengile zilandelayo kwigridi yakho, usebenzisa isikwere ngasinye njengeyunithi enye.
