QA na OT zote mbili ziko mlalo, kwa hivyo QA ni sambamba na OT. Kwa hiyo, QATO ni mstatili. Eneo la mstatili QATO ni QAmara QO au 2-0times12-024.Kwa kuwa AT ni sawa na TB, tunaweza kuchukulia AT kama urefu wa pembetatu ATB na TB kama msingi. Eneo la pembetatu ATB ni frac12times TBtimes AT frac12times12-2times12-0 frac12times10times1260.Eneo la QABO ni jumla ya maeneo ya mstatili QATO na pembetatu ATB, au 246084.
