Unit thiab cov ntsiab lus ntawm thaj chaw thiab cheeb tsam yog tseem ceeb rau lej vim lawv yog lub cev ntawm kev ua lej. Lawv yog lub hauv paus rau kev nkag siab lwm yam ntawm geometry xws li ntim thiab lej theorems uas pab peb nkag siab txog algebra, trigonometry, thiab suav lej.
Ntxiv mus, vim li cas nws tseem ceeb rau kev ntsuas ib puag ncig thiab cheeb tsam?
Perimeter thiab cheeb tsam yog ob tseem ceeb thiab cov ntsiab lus tseem ceeb ntawm lej. Perimeter yog a ntsuas ntawm qhov kev ncua deb nyob ib ncig ntawm ib daim duab thiab cheeb tsam muab peb lub tswv yim ntawm ntau npaum li cas deg lub puab npog.
Tom qab ntawd, lo lus nug yog, koj piav qhia thaj chaw li cas? Thaj chaw yog lub sij hawm siv los txhais cov nqi ntawm qhov chaw nqa los ntawm 2D duab lossis nto. Peb ntsuas cheeb tsam nyob rau hauv square units: cm² los yog m². Thaj chaw yog xam los ntawm kev muab qhov ntev ntawm ib daim duab los ntawm nws qhov dav.
Ib yam li ntawd, qhov tseem ceeb ntawm cheeb tsam yog dab tsi?
Thaj chaw yog ib lo lus lej txhais raws li qhov chaw ob sab uas coj los ntawm ib qho khoom, sau tseg Study.com, ntxiv tias kev siv cheeb tsam muaj ntau yam kev siv hauv tsev, ua liaj ua teb, architecture, science, thiab txawm tias ntau npaum li cas cov ntaub pua plag koj yuav tsum tau npog cov chav hauv koj lub tsev.
Yuav ua li cas koj nrhiav tau lub perimeter muab lub cheeb tsam?
Perimeter ntawm Rectangle
- Nco ntsoov cov qauv rau ib puag ncig thiab thaj tsam ntawm ib daim duab plaub. Qhov cheeb tsam ntawm ib daim duab plaub yog a = ntev * dav, thaum lub perimeter yog p = (2 * ntev) + (2 * dav)
- Hloov cov nqi paub rau hauv cov qauv hauv cheeb tsam. 36 = 4x w.
- Hloov cov nqi rau qhov ntev thiab qhov dav rau hauv cov qauv perimeter.

Dab tsi yog thaj chaw ntawm pej xeem kev hloov pauv thiab vim li cas nws thiaj li muaj txiaj ntsig thaum kawm txog pej xeem?
Population dynamics yog ceg ntawm lub neej sciences uas kawm txog qhov loj thiab hnub nyoog muaj pes tsawg leeg ntawm cov pejxeem raws li dynamical systems, thiab cov txheej txheem lom thiab ib puag ncig tsav lawv (xws li yug thiab tuag tus nqi, thiab los ntawm kev nkag teb chaws thiab emigration)
Koj pom thaj tsam thiab ib puag ncig hauv lej li cas?
Cov mis rau ib puag ncig ntawm ib lub duab plaub feem ntau sau li P = 2l + 2w, qhov twg l yog qhov ntev ntawm lub duab plaub thiab w yog qhov dav ntawm lub duab plaub. Qhov cheeb tsam ntawm daim duab ob sab piav qhia txog tus nqi ntawm cov duab npog. Koj ntsuas thaj tsam hauv square units ntawm qhov loj me
Vim li cas thiaj tseem ceeb heev rau cov neeg nyob hauv thaj chaw los kawm txog cov pejxeem ntawm ib lub tebchaws?
Vim cov pej xeem muaj kev cuam tshuam loj heev rau peb lub neej, nws yog ib feem tseem ceeb ntawm thaj chaw.Geographers uas kawm tib neeg cov pej xeem tshwj xeeb tshaj yog nyiam cov qauv uas tshwm sim dhau sijhawm. Lawv kawm cov ntaub ntawv xws li muaj pes tsawg tus neeg nyob hauv ib cheeb tsam, yog vim li cas tib neeg nyob qhov twg lawv ua, thiab cov pej xeem hloov pauv li cas
Vim li cas cov suab puam tseem ceeb rau ib puag ncig?
Lub qhuav qhuav ntawm cov suab puam pab txhawb kev tsim thiab concentration ntawm cov zaub mov tseem ceeb. Gypsum, borates, nitrates, poov tshuaj thiab lwm yam ntsev tsim nyob rau hauv cov suab puam thaum dej nqa cov minerals evaporates. Cov cheeb tsam suab puam kuj tuav 75 feem pua ntawm cov roj cia hauv ntiaj teb
Vim li cas txoj kev kawm txog kev xeeb tub thiab cov yam ntxwv tseem ceeb?
Heredity yog ib qho tseem ceeb rau tag nrho cov kab mob uas muaj sia nyob vim nws txiav txim siab tias yam twg tau dhau los ntawm niam txiv mus rau tus menyuam. Cov yam ntxwv zoo tau dhau mus ntau zaus thiab dhau sijhawm tuaj yeem hloov tau ib hom. Cov kev hloov pauv ntawm qhov zoo tuaj yeem tso cai rau cov kab mob hloov mus rau ib puag ncig tshwj xeeb kom muaj sia nyob zoo dua
