Nws yog npaum li cas?

Feem ntau hauv World Wide Web, lo lus nug yog: "Ib puas leej yog ntau npaum li cas?" Nws zoo li nws yuav yooj yim dua? Tab sis, raws li kev xyaum qhia, tsis yog txhua tus muaj lub tswv yim ntawm lub tswvyim no.

Qhov loj tshaj plaws hauv kev xav ntawm ib lub weave yog lub sij hawm uas qhov no yog ib qho kev ntsuas ntawm cheeb tsam ntawm thaj av thaj av. Nyuam qhuav pib, lo lus "ar" tau siv ntau zaus (nws yuav tsum tsis meej pem nrog ib evkawj!), Thiab lo lus "weaving" yog ib qho kev qhia meej meej.

Niaj hnub no, ntau zaus nyob rau hauv xov xwm thiab hauv Internet muaj cov ntawv, piv txwv li, tau txais cov ntaub ntawv xws li ib puas square meters nyob rau hauv lub suburbs nqi txog 7 txhiab daus las. Rau kev sib piv - tib cheeb tsam nyob rau hauv lub Samara outback muaj ib tug nqi ntawm 25 txhiab rubles.

Tab sis yuav kom pom tau koj tus kheej lub tswv yim dab tsi, koj yuav tsum paub, ntawm chav kawm, nws yog pes tsawg square metres koj tau txais? Thiab yog nws tau tso ib lub tsev, ib da dej, ib lub vaj nyob rau hauv xws li ib seem - ib puas square metres?

Saib tom qab, koj tuaj yeem nrhiav tau cov ntaub ntawv xws li: xyoo dhau los ntawm Soviet Union, qhov loj ntawm ib lub caij ntuj sov lub caij ntuj sov thaj chaw - 6 acres raug saws. Ntawm lub vev xaib no tau ua ib lub tsev, ib chav da dej, ib qho thiab ib lub vaj zaub me me.

Tab sis txawm tias ib puas ntawm thaj av, yog tias qhov chaw no siv los ua neeg ntse, nws tuaj yeem coj nws tus tswv lag luam loj loj: piv txwv li, nws tuaj yeem cog qoob loo los yog nyuj, muab pov tseg, apiary, tsev cog qoob los sis mini-hoobkas rau cov cib. Qhov no yog qhov qhia tau hais tias muaj nqi li cas rau thaj av.

Yuav tsis cuam tshuam rau tus nyeem ntawv, tsis txhob cuam tshuam txog ntawm lo lus nug posed: "Weaving yog npaum li cas?" - peb yuav piav qhia. Sotka yog ib puas square meters.

Tom qab tag nrho, txawm tias tsuas yog mloog cov lus no, koj tus kheej tuaj yeem kwv yees: ib puas ntawm thaj av - ntau npaum li cas? Lo lus hais rau nws tus kheej. Tej zaum, qhov no yog vim li cas lub ntsiab lus tsis tau txhais hais tias "ar" tawm hauv kev hais lus, muab kev rau tib neeg lo lus - "weaving".

Yuav ua li cas koj thiaj paub xam txog thaj av? Yog hais tias nws muaj ib lub xwmfab lossis duab zoo, ces, raws li cov cai ntawm geometry, koj yuav tsum tau muab cov kev txwv: ntev thiab dav. Tau kawg, ua ntej ua tib zoo ntsuas nrog kev pab los ntawm kev siv kab xev.

Piv txwv, qhov ntev yog 48 meters, thiab qhov dav yog 26. Tshaj 48 meters los ntawm 26 meters.

48m H26m = 1248 square meters. M

Qhov tshwm sim yog hais nyob rau hauv square metres, qhov no yog ib daim duab loj, uas yog tsis txaus nyiam siv. Tab sis peb twb paub lawm hais tias peb siv tau qhov kev ntsuas loj, thiab peb kuj paub tias nws yog qhov ntau npaum li cas.

Yog li ntawd, peb yooj yim faib cov txiaj ntsim los ntawm ib puas thiab tau txais pes tsawg tus xov tooj ntawm puas. Leej twg tsis paub sib faib los ntawm ib puas, nws yuav tsum tau prompted: nws yog ib qho yooj yim, koj yuav tsum suav ob cov duab rau ntawm sab xis thiab muab ib qho tsis nco qab. Nyob rau hauv peb cov ntaub ntawv, qhov no yuav zoo li no: 1248 sq. M = 12.48 ar = 12.48 acres.

Qhov teeb meem no nyuab dua yog tias lub voj voog los yog oval, voos plaub ceg los yog polygonal, los sis txawm yooj yim incomprehensible, nrog ib tus contoured contour.

Tshawb ntawm thaj chaw ntawm ib qho chaw uas muaj peb sab los sis ib qho chaw hauv daim ntawv ntawm ib qho trapezoid, ib qho rhombus los yog ib qho kev ntsuas mus rau cov neeg uas daws teeb meem nrog geometry nrog kev hlub, thiab nws yuav tsis yooj yim. Thiab thaj chaw ntawm lub voj voog, dhau lawm, tsis yog qhov teeb meem los xam. Feem ntau thaum ntsuas, koj yuav tsum faib seem ntawm lub siab mus rau hauv ntau cov duab plaub feem ntau los yog cov triangles, coj cov kev ntsuas hauv txhua cheeb tsam me me, ua cov laij leb thiab ntxiv lawv ua ke.

Tab sis nws yuav luag tsis paub lub cheeb tsam ntawm ib qhov chaw ntawm cov duab tsis sib thooj ntawm nws tus kheej. Tsis tas li ntawd, nws tsis yog qhov tsim nyog los daws cov teeb meem, yog tias nws muaj kev txhawj xeeb. Tom qab ntawd nws yog qhov zoo tshaj plaws los mus siv cov kev pab ntawm ib tug neeg soj ntsuam. Cov kws tshaj lij yuav muab lawv cov neeg muas zaub rau thaj tsam uas tsis tau hais tawm hauv cov square meters, tab sis twb tau muab cov kev ntsuas hauv cheeb tsam ua. Lawv twb paub, nws yog ntau npaum li cas!

Feem ntau cov av soj ntsuam tsis txawm siv thawj tus txheej txheem roulette - hnub no muaj ntau txoj hau kev ntsuas ntawm cheeb tsam loj. Niaj hnub nimno GPS tshuab tso cai rau koj los txiav txim xyuas saib xyuas qhov chaw ntawm lub cheeb tsam ntawm koj qhov chaw kom ze tshaj plaws li ntawm 100th. Tsis ntog lawm ib nrab-centimeter!

Nyob rau hauv xaus, nws yog ib nqi sau cia hais tias ib puas hectares ua li 1 hectare, uas yog customary rau cov ntaub ntawv "his".
