Bedka ama Badka Qardhaas waxaa loo xisaabi karaa afar qaab:

  1. Barbaroolayaasha oo dhan, Waxa ay ka samaysmaan Salka a, Waxa ay la jaan qaadeeysaa dhinacyada iyo jooga h:
     A = a \cdot h,
  2. Adigoo dhexroorka dheer ku dhifta d_1 Dhexroorka gaaban d_2 Oo aad markaas uqaybiso
    \frac{\overline{AC} \cdot \overline{SB}}{2} = \frac{\overline{AC} \cdot \overline{BD}/2}{2} = \frac{\overline{AC} \cdot \overline{BD}}{4}
    Adigoo laba laaba si aan u helno
     A = {{d_1 \cdot d_2} \over {2}} = \frac{\overline{AC} \cdot \overline{BD}}{2},
  3. Adigoo ku dhufanaya goobada p Gacanka r Wareegeeda
    4 \cdot \frac{a \cdot r}{2} = 2 \cdot a \cdot r = p \cdot r.
     A = p \cdot r,
  4. Ugudamayntii adigoo uxisaaba sida afar xafal a Xaglaha gudaha adigoo isku dhufta
    {a^2 \cdot \sin\alpha} = a \cdot (a \cdot \sin\alpha) = a \cdot h
     A = {a^2 \cdot \sin\alpha} = {a^2 \cdot \sin\beta}.
