- Momwe mungawerengere masikweya mita amitundu yosiyanasiyana?
- Kodi mungapite bwanji kuchokera ku mita yayitali kupita ku njira zina?
Pulogalamu ya mita lalikulu ndiyeso yoyeserera, imagwiritsidwa ntchito kuyeza mawonekedwe azinthu kapena zinthu ziwiri ngati khoma, nyumba kapena chitseko.
Mita mita ndi dera lomwe lili mkati mwa sikweya yomwe mbali zake zimakhala mita imodzi. Amawonetsedwa ndi chizindikiro "m²".
Mamita apakati amawerengedwa mosiyanasiyana kutengera mawonekedwe a dera lomwe mukufuna kudziwa: lalikulu, kansalu, bwalo. Kuti muchite izi, ndikofunikira kudziwa momwe masamu amawerengeredwera masikweya mita iliyonse yazithunzi.
Kuti mupeze malo amunthu wosazolowereka, chiwerengerocho chiyenera kugawidwa m'magulu ena monga mabwalo kapena ma triangles. Kenako ma square metres a ziwerengerozi amawerengedwa ndi mafomu omwe amadziwika, amawonjezedwa ndipo kuchuluka kwake ndikomwe kuli malo okwanira ma square metres osadziwika bwino.
- Itha kukutumikirani: Mayunitsi amiyeso
Momwe mungawerengere masikweya mita amitundu yosiyanasiyana?
- Kuwerengetsa lalikulu mita lalikulu kapena amakona anayi
Kuwerengetsa mita yayitali ya, mwachitsanzo, khoma lalikulu, kutalika ndi mulifupi kwa khoma liyenera kutengedwa ndi tepi. Ndiye mfundo zonse ziwirizi zimachulukitsidwa ndipo zotsatira zake zazitali za malowa zimapezeka.
- Terengani masentimita lalikulu lachitatu laling'ono
Kuti muwerengetse mita yaying'ono yamakona atatu akumanja, muyenera kuchulukitsa muyeso womwe muli nawo ndikugawa zotsatirapo ziwiri.
Mwachitsanzo: mu kansalu kachithunzi: 5 x 7 = 35 mita ichulukitsidwa. Kenako gawani zotsatirazi ndi awiri: 35/2 = 17.5 m².
- Terengani ma square mita amtundu wosakanikirana
Kuti muyese masitepe apamakona osasinthasintha, muyenera kusintha ma triangles osasinthika kukhala omwewo kenako ndikuwayesa.
Kuti muchite izi, mzere uyenera kutengedwa kuchokera pakona iliyonse yamakona atatu kupita mbali inayo kuti mzerewo udule mbali ya kansanjayo pakona la 90 °. Kenako amawerengedwa mofananamo ndi ma katatu oyenera.
- Werengani masikweya mita wa bwalo
Kuti muwerengetse bwalo lalikulu mita, bwalolo liyenera kugawidwa m'magawo awiri ofanana ndendende. Chotsatira, mzere uyenera kujambulidwa pakati, ndikupanga kansalu kolondola.
Muyenera poyamba kuwerengera dera la bwalolo. Kuti muchite izi, utali wozungulira bwalolo umayezedwa ndikuchulukitsidwa ndi awiri.
Mwachitsanzo: Ngati utali wozungulirawu ndi wofanana ndi masentimita atatu, tiyenera kuchulukitsa 3 x 2 = 6. Chotsatira chake ndi kukula kwa bwalolo. Pomaliza, nambala iyi iyenera kuchulukitsidwa ndi 3.14 (nambala yotchedwa pi). Kutsatira chitsanzo ichi 6 x 3.14 = 18.84 cm².
Kodi mungapite bwanji kuchokera ku mita yayitali kupita ku njira zina?
- Pezani muyeso mu mapazi apakati. Izi zimagwiritsidwa ntchito kutembenuza mayunitsi ena kukhala ma mita lalikulu ndikuwerengera. Chifukwa chake, phazi limodzi limafanana ndi 0,093 mita mita (m²). Kenako, muyenera kuyeza dera lomwe mukufuna kuwerengera ndi tepi muyeso. Mwachitsanzo, m'lifupi mwa khoma. Poganizira kuti khoma ili ndi 2.35 m², mtengowu uyenera kuchulukitsidwa ndi 0.093 ndipo zotsatira zake zizikhala zazitali.
- Pezani muyeso m'mayadi akulu. Kuti mupeze muyeso m'mabwalo apakati, muyenera kuchulukitsa mtengo wopezeka ndi 0.84. Mu chitsanzo chomwe chatchulidwa pamwambapa, chulukitsani 2.35 x 0.84 ndipo zotsatira zake zikuwonetsedwa m'mabwalo akulu.
- Pezani muyeso wa maekala. Kuti muchite izi, zotsatirazi ziyenera kuchulukitsidwa ndi 4.05 ndipo zotsatirazi zidzafotokozedwa maekala.
- Pitirizani ndi: Mayunitsi opangidwa
