Siyithola kanjani indawo yesikwele?
I-rectangle isakhiwo esivaliwe esinobubanzi obubili obunama-quadrilateral anama-engeli amane aqondile (90 degrees). Izinhlangothi eziphambene zesikwele ziyalingana futhi zilingana ngobude. Ngokuvamile, ubude bezinhlangothi ezinde bubizwa ngokuthi ubude be-rectangle futhi ubude bezinhlangothi ezimfushane bubizwa ngokuthi ububanzi/ububanzi be-rectangle. Indawo ye-rectangle ibalwa ngokuphindaphinda ubude nobubanzi be-rectangle. Ngokwesibonelo, Uma ubude bokunxande bungu-l futhi ububanzi bokunxande bungu-w khona-ke indawo yokunxande = (l x w). Uma zonke izinhlangothi zesikwele zinobude obulinganayo khona-ke kuthiwa isikwele. Ngakho-ke, isikwele siyindaba ekhethekile yesikwele.
