Umxholo
- Ungazibala njani iimitha zesikwere zamanani ejiyometri ahlukeneyo?
- Uhamba njani ukusuka kwisikwere seemitha ukuya kwamanye amanyathelo?
Inkqubo ye- Isikwere semitha sisixhobo esisisiseko sokulinganisa, sisetyenziselwa ukulinganisa umphezulu okanye izinto ezinemilinganiselo emibini njengodonga, indlu okanye ucango.
Imitha yesikwere yindawo ephakathi kwesikwere macala ayo alinganisa imitha enye. Zichazwe ngophawu "m²".
Isikwere seemitha sibalwa ngeendlela ezahlukeneyo kuxhomekeke kubume bendawo ofuna ukuyazi: isikwere, unxantathu, isangqa. Ukwenza oku, kubalulekile ukwazi ifomula yokubala iimitha zesikwere kumfanekiso ngamnye wejometri.
Ukufumana indawo yomntu ongaqhelekanga, inani elo kufuneka lahlulwe libe ngamanye amanani afana nezikwere okanye oonxantathu. Ke iimitha zesikwere zala manani zibalwa ngeefomula ezaziwayo, ziyongezwa kwaye inani eliphumayo yindawo iyonke kwiimitha zesikwere zelo nani lingaqhelekanga.
- Ingakukhonza: Iiyunithi zomlinganiso
Ungazibala njani iimitha zesikwere zamanani ejiyometri ahlukeneyo?
- Bala iimitha zesikwere okanye uxande
Ukubala iimitha zesikwere, umzekelo, udonga lwesikwere, ukuphakama nobubanzi bodonga kufuneka kuthathwe ngomlinganiselo wekhasethi. Ke amaxabiso aphindaphindiwe kwaye iziphumo zeemitha zesikwere zale ndawo ziyafunyanwa.
- Bala iimitha ezisikwere zonxantathu ofanelekileyo
Ukubala iimitha zesikwere zoonxantathu basekunene, kuya kufuneka uyiphindaphinde imilinganiselo onayo emva koko uwahlule ngeziphumo ezibini.
Umzekelo: kunxantathu emfanekisweni: 5 x 7 = 35 yeemitha iyakwandiswa. Emva koko yahlula eso siphumo ngababini: 35/2 = 17.5 m².
- Bala iimitha zesikwere zoxande olungaqhelekanga
Ukulinganisa i-footage yesikwere soxande abangaqhelekanga, kuya kufuneka uguqule oonxantathu abangafaniyo abaqhelekileyo kwaye ubalinganise.
Ukwenza oku, umgca kufuneka utsalwe nakweyiphi na ikona kanxantathu uye kwelinye icala ngendlela eya kuthi umgca usike elo cala likanxantathu kwi-angle ye-90 °. Emva koko ibalwa ngendlela efanayo noonxantathu abalungileyo.
- Bala iimitha zesikwere zesangqa
Ukubala iimitha zesikwere zesangqa, isangqa kufuneka sahlulwe sibe ziihafu ezimbini ezilinganayo. Emva koko, umgca kufuneka utsalwe ezantsi, wenze unxantathu ofanelekileyo.
Kufuneka uqale ubale indawo yesangqa. Ukwenza oku, irediyadi yesangqa iyalinganiswa kwaye iphindaphindwe kabini.
Umzekelo: ukuba le radius ilingana neesentimitha ezi-3, kufuneka siphindaphinde 3 x 2 = 6. Esi siphumo sisangqa sesangqa. Okokugqibela, eli nani kufuneka liphindaphindwe ngo-3.14 (inani elaziwa njenge-pi). Ukulandela lo mzekelo 6 x 3.14 = 18.84 cm².
Uhamba njani ukusuka kwisikwere seemitha ukuya kwamanye amanyathelo?
- Fumana umlinganiso ngeenyawo zesikwere. Oku kusetyenziswa ukuguqula ezinye iiyunithi zibe ziimitha zesikwere kwaye uzibale. Ke, inyawo elinye lilingana no-0.093 square metres (m²). Emva koko, kuya kufuneka ulinganise indawo ofuna ukuyibala ngetape measure. Umzekelo, ububanzi bodonga. Ukuthatha ukuba olu donga lilinganise i-2.35 m², eli xabiso kufuneka liphindaphindwe nge-0.093 kwaye iziphumo ziya kuba ziinyawo ezikwere.
- Fumana imilinganiselo kwiiyadi zesikwere. Ukufumana umlinganiso kwiiyadi zesikwere, kuya kufuneka uphindaphinde ixabiso elifunyenwe ngu-0.84. Kumzekelo okhankanywe apha ngasentla, phinda-phinda u-2.35 x 0.84 kwaye iziphumo zichazwe kwiiyadi ezikwisikweri.
- Fumana umlinganiso kwiihektare. Ukwenza oku, iziphumo kufuneka ziphindaphindwe nge-4.05 kwaye iziphumo ziya kuboniswa kwiihektare.
- Qhubeka ne: Iiyunithi ezifunyenweyo
