ABCD is a quadrilateral with `vec(AB) = veca, vec(AD) = vecb and vec(AC)=2veca+3vecb.` If its area is `alpha` times the area of the parallelogram with AB and AD as adjacent sides, then `alpha=`

ABCD is a quadrilateral with vec(AB)= vec(a), vec(AD)= vec(b) and vec(AC)= 2 vec(a) + 3vec(b) . If its area is alpha times the area of the parallelogram with AB, AD as adjacent sides, then alpha =

If ABCD is a quadrilateral with vec AB = vec a, vec AD = vec b and vec AC = 2 vec a + 3 vec b . If its areas is alpha times the area of the parallelogram with AB, AD as adjacent sides than alpha =

(ABCD is a quadrilateral with )/(AB)= .If the area of parallelogram ABCD is p xx the area of parallelogram ABCD is p xx the area of the parallelogram with AB,AD as adjacent sides,then p is equal to

If ABCD is a parallelogram then vec(AB) + vec(AD) + vec(CB) + vec(CD) = …………………… .

ABCD is a quadrilateral and let AB=vec a ,AD=vec b,AC=mvec a+nvec b then the area of the quadrilateral is

In a quadrilateral ABCD, vec(AB)=vec(b),vec(AD)=vec(d) and vec(AC)=m vec(b)+p vec(d)(m+p ge1) . The area of the quadrilateral ABCD is ……………..

ABCD is a quadrilateral with bar(AB)=bar(alpha)andbar(AD)=bar(beta)andbar(AC)=2bar(alpha)+3bar(beta). If the area of the quadrilateral is lambda times the area of the parallelogram with bar(AB)andbar(AD) as adjacent sides, then prove that lambda=(5)/(2)
