Lub perimeter ntawm ib tug quadrilateral yog tag nrho ntev ntawm nws ciam teb Piv txwv li, lub perimeter ntawm ib tug plaub ntug ABCD yuav qhia tau hais tias, Perimeter=AB + BC + CD + DA. Qhov no txhais tau tias yog tag nrho cov sab ntawm lub quadrilateral paub, peb tuaj yeem tau txais nws ib puag ncig los ntawm kev ntxiv tag nrho nws sab.

Koj pom qhov ib puag ncig thiab thaj tsam ntawm plaub fab li cas?

Peb paub tias qhov ib puag ncig ntawm quadrilateral=tus lej ntawm txhua sab ntawm plaub fab ABCD=(AB + BC + CD + DA) Peb muaj tag nrho cov txiaj ntsig rau luas=(8 + 5 + 13 + 10) cm=36 cm. Yog li, peb tau txais thaj tsam ntawm plaub fab li $69.7c{{m}^{2}}$ thiab ib puag ncig li 36 cm.

Puas yog cov qauv plaub npaug?

Area of General Quadrilateral Formula= 1/2 x diagonals length x (sum of the height of two triangles).

Puas Quadrilaterals 4 sab?

A quadrilateral is a polygon nrog plaub sab. Muaj ntau yam tshwj xeeb ntawm quadrilateral. Ib qho parallelogram yog ib lub quadrilateral nyob rau hauv uas ob khub ntawm opposite sab yog parallel.

koj txhais li cas los ntawm quadrilateral?

A quadrilateral yog a polygon uas muaj plaub sab. (Qhov no kuj txhais tau hais tias ib lub quadrilateral muaj raws nraim plaub vertices, thiab raws nraim plaub lub ces kaum.)
