Okuqukethwe
Okushicilelwe kwethula izibali eziku-inthanethi namafomula okubala indawo kanxande ngokuya ngedatha ehlukahlukene yokuqala: ngezinhlangothi (ubude nobubanzi) noma ama-diagonal kanye ne-engeli ephakathi kwawo.
Okuqukethwe
Ukubalwa kwendawo
Imiyalo yokusetshenziswa: faka amanani aziwayo, bese ucindezela inkinobho “Bala”. Ngenxa yalokho, indawo yesibalo sosayizi oshiwo izobalwa.
1. Ngezinhlangothi (ubude nobubanzi)
Ifomula yokubala
S = a ⋅ b
2. Ngokusebenzisa ama-diagonal kanye ne-engeli ephakathi kwawo
Ifomula yokubala
Qaphela: ama-diagonal kanxande ayalingana.
