<prompt> Katika mchoro, eneo la mstatili PQRS ni 24. Kama TQ TR, eneo la pembe nne PTRS ni nini? asyukubwa 100;chora0,0--6,0--6,4--0,4--mzunguko;chora0,4--6,2;chora5.8,1.1--6.2,1.1;chora5.8,.9--6.2,.9;chora5.8,3.1--6.2,3.1;chora5.8,2.9--6.2,2.9;leboP,0,4,NW;leboS,0,0,SW;leboR,6,0,SE;leboT,6,2,E;leboQ,6,4,NE;asy  <response>: Kwa kuwa eneo la mstatili PQRS ni 24, tuchukulie kuwa PQ6 na QR4.Kwa kuwa QTTR, tuna QR2QT ili QT2. asyukubwa 100;chora0,0--6,0--6,4--0,4--mzunguko;chora0,4--6,2;chora5.8,1.1--6.2,1.1;chora5.8,.9--6.2,.9;chora5.8,3.1--6.2,3.1;chora5.8,2.9--6.2,2.9;leboP,0,4,NW;leboS,0,0,SW;leboR,6,0,SE;leboT,6,2,E;leboQ,6,4,NE;lebo6,3,4,N;lebo2,6,3,W;lebo2,6,1,W;asy Kwa hivyo, pembetatu PQT ina msingi PQ wa urefu 6 na urefu QT ya urefu 2, hivyo ina eneo frac12cdot 6cdot 2 frac12cdot 12 6. Kwa hivyo eneo la pembe nne PTRS ni sawa na eneo la mstatili PQRS ambayo ni 24 ukiondoa eneo la pembetatu PQT ambayo ni 6, au 18.
