Answer:
We are given that,
One side of a parallelogram is AB and the height is 3 units.
Let, the vertices of the parallelogram are (0,0), (a,b), (c,0) and (c,b).
Also, let the one side AB is represented by the vertices A = (0,0) and B = (a,b).
So, we have that, the co-ordinate (a,b) is 3 units up from (0,0).
Hence, the parallelogram satisfying the conditions is shown below.
