- Ubala kanjani amamitha ayisikwele wezibalo ezihlukile zeJiyomethri?
- Ungahamba kanjani ukusuka kumamitha ayisikwele uye kwezinye izinyathelo?
I- imitha eyisikwele iyunithi eyisisekelo yokukala, isetshenziselwa ukukala indawo noma izinto ezinamacala amabili njengodonga, ifulethi noma umnyango.
Imitha eyisikwele yindawo engaphakathi kwesikwele lapho izinhlangothi zazo zilinganisa imitha elilodwa. Zivezwa ngophawu "m²".
Amamitha ayizikwele abalwa ngezindlela ezahlukahlukene kuya ngesimo sendawo ofuna ukuyazi: isikwele, unxantathu, indilinga. Ukuze wenze lokhu, kubalulekile ukwazi ifomula yezibalo yokubala amamitha ayisikwele wenani ngalinye lejometri.
Ukuthola indawo yesibalo esingajwayelekile, isibalo kufanele sihlukaniswe sibe ezinye izibalo ezifana nezikwele noma onxantathu. Ngemuva kwalokho amamitha ayisikwele alezi zibalo abalwa namafomula aziwayo, ayangezwa futhi inani eliholelwayo yindawo ephelele kumamitha-skwele wesibalo esingajwayelekile.

Ubala kanjani amamitha ayisikwele wezibalo ezihlukile zeJiyomethri?
- Bala amamitha ayizikwele wesikwele noma unxande
Ukubala amamitha ayizikwele, ngokwesibonelo, udonga oluyisikwele, ukuphakama nobubanzi bodonga kufanele kuthathwe ngesilinganiso seteyipu. Ngemuva kwalokho womabili amanani ayandiswa futhi umphumela wamamitha skwele waleyo ndawo uyatholakala.
- Bala amamitha ayisikwele onxantathu ongakwesokudla
Ukubala amamitha ayisikwele onxantathu abangakwesokudla, kufanele uphindaphinde isilinganiso osinaso bese uhlukanisa lowo mphumela ngababili.
Isibonelo: kunxantathu osesithombeni: 5 x 7 = 35 metres izokwandiswa. Bese uhlukanisa lowo mphumela ngababili: 35/2 = 17.5 m².
- Bala amamitha ayizikwele wonxande ongajwayelekile
Ukukala imidwebo eyisikwele yonxande abangajwayelekile, kufanele uguqule onxantathu abangajwayelekile baye kokujwayelekile bese ubalinganisa.
Ukuze wenze lokhu, umugqa kufanele udonswe kunoma iliphi ikhona likanxantathu uye kolunye uhlangothi ngendlela yokuthi ulayini usike lelo cala lonxantathu nge-engela ka-90 °. Bese kubalwa ngendlela efanayo nonxantathu abalungile.
- Bala amamitha ayizikwele ombuthano
Ukubala amamitha ayizikwele ombuthano, umbuthano kufanele uhlukaniswe waba izingxenye ezimbili ezilingana ncamashi. Okulandelayo, umugqa kufanele udwetshwe phakathi nendawo, wakhe unxantathu ongakwesokudla.
Kufanele uqale ubale indawo yombuthano. Ukuze wenze lokhu, irediyasi yombuthano ilinganiswa futhi iphindwe kabili.
Isibonelo: Uma le radius ilingana namasentimitha ama-3, kufanele siphindaphindeke ngo-3 x 2 = 6. Lo mphumela ububanzi besiyingi. Ekugcineni, le nombolo kufanele iphindaphindwe ngo-3.14 (inombolo eyaziwa njenge-pi). Ukulandela lesi sibonelo 6 x 3.14 = 18.84 cm².
Ungahamba kanjani ukusuka kumamitha ayisikwele uye kwezinye izinyathelo?
- Thola isilinganiso ngezinyawo eziyisikwele. Lokhu kusetshenziselwa ukuguqula amanye amayunithi abe amamitha ayisikwele futhi uwabale. Ngakho-ke, unyawo olulodwa lulingana no-0.093 square metres (m²). Ngemuva kwalokho, kufanele ulinganise indawo ofuna ukuyibala nge-tape measure. Isibonelo, ububanzi bodonga. Uma ucabanga ukuthi lolu donga lukala u-2.35 m², leli nani kufanele liphindwe ngo-0.093 bese umphumela uzoba ngamamitha ayisikwele.
- Thola isilinganiso emagcekeni ayisikwele. Ukuze uthole isilinganiso kumayadi ayisikwele, kufanele uphindaphinde inani elitholwe ngu-0.84. Esibonelweni esishiwo ngenhla, phindaphinda u-2.35 x 0.84 futhi umphumela uboniswa emagcekeni ayizikwele.
- Thola isilinganiso kumahektare. Ukwenza lokhu, umphumela kufanele uphindwe nge-4.05 futhi umphumela uzovezwa ngamahektare.
- Qhubeka: Amayunithi atholakele
