Tenganisha EFBA ndani ya mstatili wa I na pembetatu za kulia za II na III, kama inavyoonyeshwa. Eneo la mstatili I ni 6; pembetatu II ni 12 ya mstatili AGED, kwa hivyo eneo lake ni 1.5. Ndivyo ilivyo kwa pembetatu III. Hivyo, 6 1.5 1.5 9. Eneo la trapezoid EFBA ni 9 za mraba.asyukubwa 4cm,4cm;jaza0,0--1,3--1,0--cycle,lightblue;jaza1,0--1,3--3,3--3,0--cycle,lightgray;jaza3,0--4,0--3,3--cycle,lightblue;kwaint i0; i 4; ikwaint k0; k 5; kchora0,i--4,i;chorak,0--k,3;chora0,0--1,3;chora3,3--4,0;leboA,0,0,SW;leboB,4,0,SE;leboC,4,3,NE;leboD,0,3,NW;leboE,1,3,N;leboF,3,3,N;leboII,0.5,0.5;leboI,1.5,1.5;leboIII,3.4,0.5;asy
