Kalkuletar faɗi da tsayin allo
Mene ne faɗi da tsayin wurin hoto daga diagonal da rabon siffarsa?
Lissafa girman wurin hoto mai lebur na murabba'in dogo a santimita da inci, ta diagonal da rabon faɗi da tsayi da ka shigar.
Diagonal da rabon da ka zaɓa
Don 4:3, shigar da 4 da 3. Faɗi yana bin ɓangaren farko, tsayi na biyun; kalkuletar ba ya juya su da kansa. An yarda da lambobin desimal. Diagonal na sifili shi ne yanayin iyaka na girman sifili; ɓangarorin rabo biyu dole su fi sifili.
Yadda ake samun kimantawa
Idan faɗi:tsayi = a:b, diagonal na murabba'in dogon da ya dace yana da daidaitaccen rabo da √(a² + b²). Ninka diagonal ɗinka da a ko b, sannan ka raba da wannan ma'auni don samun faɗi ko tsayi a inci. Inci ɗaya daidai yake da 2.54 cm. Ana lissafa faɗin fili daga lissafin siffa kafin a zagaye lambobi.
W = D × a ÷ √(a² + b²)
H = D × b ÷ √(a² + b²)
cm = in × 2.54
A = D² × a × b ÷ (a² + b²) × 2.54²Samfurin yana nuna wurin hoto mai lebur na murabba'in dogo kawai, da diagonal da rabo da aka shigar. Ba ya haɗa firam, matattaka, sararin sakawa, lankwasawa, kusurwoyi masu zagaye, ramuka ko yanke hoto. Ba ya lissafa yawan piksel a tsayi ko nisan kallo. Duba ainihin girman waje dabam; ba garantin cewa na'ura za ta shiga sarari ba ne.

Duba misalin da aka cika
Misalin da aka zaɓa: diagonal inci 10 da faɗi:tsayi 4:3 suna ba da inci 8 × 6, ko 20.32 × 15.24 cm. Faɗin filin murabba'in dogon shi ne 309.6768 cm², diagonal kuma 25.4 cm. Waɗannan bayanan misali ne, ba shawarar girman allo ko rabonsa ba.
