Imvamisa isizukulwane esidala siyakwazi konke lokhu. Futhi sebekade bakwazi ukubala inani lamamitha ngekhulu. Abamele isizukulwane esincane, esikhathini esiningi, bebengakaze bezwe igama elithi "ukuluka", futhi bebengazazi izindlela zokubala. Ngempela, kumadokhumenti asemthethweni asemthethweni ngokuvamile awemukelwa ukusebenzisa lo mqondo, lapho indawo ibalwa kuphela kumahektha, hhayi ngisho nase-ara. Ngakho-ke, liyini ikhulu lomhlaba futhi lingabalwa kanjani?
Indawo Elula
Kunezindawo ezahlukahlukene zomhlaba. Imvamisa zijamo elilula lejometri: isikwele noma isikwele. Kepha kukhona okuhlukile uma isiza siyi-trapezoid noma i-parallelograph. Esiqeshini somhlaba esinobukhulu obungunxande noma wesikwele, kulula kakhulu ukubala indawo yamamitha-skwele ayikhulu. Ifomula eyodwa kuphela yejometri ezosiza ukuyithola. Ifomula yendawo yesikwele noma isikwele.
Indawo yamamitha skwele ayikhulu isayizi wamakhulu ayikhulu.
Njengoba wazi, izinto ezikhethekile zisetshenziselwa ukubala indawo yomhlaba. Zitholakala izazi zezolimo nama-agronomist, ama-cartographers kanye nezinye izisebenzi ezenza lezo zilinganiso. Ungasho ukuthi ungomunye wabo. Kodwa ukuze ubala indawo eyikhulu yamamitha skwele, ungakhathazeki ngokungabikho kwamathuluzi ayinkimbinkimbi. Ngeke nje adingeke. Konke okudingayo:
- noma yiziphi izikhonkwane ezine;
- i-roulette (emfushane kakhulu);
- ipeni nencwajana.
Faka izikhonkwane kuwo wonke amagumbi ezwe. Ukusuka isikhonkwane kuya kwesikhonkwane, ukukala yonke imingcele yendawo ngesilinganiso setheyipu. Uma zonke izinhlangothi zilingana ngobude, khona-ke lesi yisikwele. Uma izinhlangothi ezimbili ezimfishane ziyalingana, njengoba zinjalo izinhlangothi ezinde, khona-ke isikwele. Rekhoda imiphumela kubhukwana. Ake sithi uhlangothi olulodwa luphendukele emamitha angama-30, kanti lona olungamamitha angama-40. Lapho-ke kudingeka ukuthi ziphindaphindeke lezi zinombolo. Kwavela amamitha skwele ayi-1200. Elikhulu liyamamitha ayi-100. I-1200 ihlukaniswe yi-100, sithola inombolo ye-12. Konke, ubungako bezwe babungamahektare ayi-12. Uma izinhlangothi zilingana (isikwele), khona-ke noma yiziphi ezimbili zazo ziphindaphindeka omunye ngomunye futhi zihlukanise ngekhulu.
Awungeke usebenzise i-roulette, kepha ngezandla zakho zakha ikhampasi yemitha yokhuni. Kusukela kusikhonkwane, imitha ngemitha, ukuhamba nokubala. Kubalulekile ukuthi ibanga phakathi kwemikhawulo yemilenze yekhampasi liyimitha eyodwa! Kumamitha skwele ayikhulu omhlaba ayi-100 metres.
Iziza eziyinkimbinkimbi
Kuyenzeka. Lapho isayithi inesimo esiyinkimbinkimbi (hhayi isikwele noma isikwele), isibonelo, i-trapezoid noma, ngokuvamile, isiyingi. Nawa amanye amafomula wejometri asiza. Isibonelo, isayithi lisesimweni sohlaka.
Udinga ukuthola kuphela ubude ohlangothini olukhulu. Kepha manje kufanele uthole ukuphakama. Uzothola le ndawo uma uphinda ubude ngobude. Lezi izindlela ezilula zokubala indawo yepharallelograph. Isebenza futhi ekubaleni indawo ye-rhombus.
Ukuphakama kufanele kube ngokwengxenye ohlangothini olukhulu. Lokho wukuthi, kwakhela i-angle yama-degree angama-90 naye, okungenani ngamehlo.
Uma une-trapezoid, kuzodingeka uthole ubude bezisekelo zayo. Okuyisisekelo yimigqa emibili efanayo. Kungemva kwalokho kuphela kokubheka ukuphakama. Uzothola indawo ngefomula: uhhafu wesamba sezisekelo uphindwe ukuphakama. Kwikhalori, izobukeka kanjena: isisekelo sokuhlanganisa isisekelo, iphindaphindwe ukuphakama, iphindaphindwe ngo-0,5. Konke, indawo ikhona.
Kunezigaba eziyindilinga, kepha lokhu kuyivelakancane kakhulu. Kuyadingeka ukuthola indawo yombuthano. Imisakazo ibanga ukusuka enkabeni kuya emngceleni wesiyingi. Uzothola indawo ngefomula: 3.14 (Pi) iphindaphindwe ngobude berediyo ekalwe (iphindwe kabili ngokwayo).
Izindawo ze-Ellipsoidal (oval) nazo azivamile. Okuyinkimbinkimbi ngokwengeziwe, kufanele ubheke maphakathi ne-oval nobude bezimbazo. Phinda uhhafu we-axis enkulu ngesigamu sezinto ezincane, bese uphinda ngo-3.14. Kwenziwe.
Kunezigaba ezine-quadrangular lapho izinhlangothi zonke zihlukile. Lokho wukuthi, ngokwesibonelo, eyodwa ngamamitha ayi-19, enye ingama-27, eyesithathu ingama-30, kuthi owesine kube ngama-50. Kungcono uma ikona elilodwa liqonde. Kuzofanele silinganise zonke izinhlangothi. Lapho, imvamisa, kusetshenziswa isono kanye nemvelo, okungabalwa esizeni. Noma kunjalo, kukhona okokubala okuku-inthanethi okuvumela ukuthi useshe indawo yama-quadrangles anjalo nhlangothi zonke.
Lapho indawo inkulu kakhulu, ubukhulu babalwa kumahektha. Amahektare ayi-100 = ihektha eli-1 = amamitha ayi-10,000.
Amakhulu nendawo
Ubungako besakhiwo ngamakhulu angatholakala kumadokhumenti noma kukalwe ngokuzimela ngokukha imitha.
Uma wazi inani lamakhulu
Uma wazi inani lamahektare ezindlu zangasese noma izingadi, kodwa ngokuzumayo wafuna ukubala indawo yesakhiwo, bese usebenzisa ukubalwa okuphindayo. Isibonelo, kunamahektare ayisithupha. Phinda eziyisithupha ngekhulu. Kuvela ukuthi angamamitha-skwele angama-600 - nayi ndawo. Uma ubukhulu besakhiwo singamahektare ayi-10, khona-ke ngamamitha kuzoba yi-1000.
Lapho kungekho datha
Uma ungazi noma inani le-acres noma le ndawo, khona-ke kulokhu kufanele wazi, yindawo kuphela. Yazi futhi: izikhonkwane, izilinganiso eziseceleni ne-arithmetic. Kokubili indawo nenombolo yamahektare izokwaziwa uma ufuna.
Ukuthola ukuthi: amamitha angamamitha-skwele ayikhulu angenza indawo usebenzisa i-inthanethi, eshayela inani lamamitha skwele ayikhulu lapho. Isibonelo, amahektare angama-63,5. Le ndawo izoba ngamamitha skwele angama-6350.
