Dear student

No it is not possible to construct a quadrilateral ABCD with the given side.

Consider ,

AB = 3cm, AD = 6cm, BD = 9cm

Property of triangle states that sum of two sides should always be greater than the third side.

Here 3 + 6 = 9 not strictly greater than the third side.

therefore not possible to construct the quadrilateral ABCD.
