Answer
Steps of construction :
Draw AB = 5.1 cm as base.
At A, with radius 2.8 cm and at B with radius 3.5 cm draw two arcs intersecting each other at O.
Join AO and produce it till C such that OC = AO = 2.8 cm and join BO and produce it till D such that OD = BO = 3.5 cm.
Join A, B, C and D forming parallelogram ABCD.
We know that locus of point equidistant from two lines is the angle bisector of the two lines.
From figure,
BE is the angle bisector of ∠ABC which meets DC at P.
