Your answer;
ABCD is a ||gm, therefore, AD = BC
and given OB/OD = 1/2
In triangle AOD and BOD,
AD || BC
AD || BE
thus, ADO = OBE [ alternate interior angles ]
DAO = OEB
triangle ADO is similar to triangle EBO
OD/OB = AD/BE
taking reciprocals from both sides,
OB/OD = BE/AD
1/2 = 1.5/AD [ But AD = BC ]
1/2 = 1.5/BC
BC = 3cm.
