Answer:
Possible coordinates of square PQRS is

And many more sets of coordinates are possible.
Explanation:
Diagram of the given scenario is shown below,
Given that,
Perimeter of square is
.
Area of square is

So,
Perimeter of a square =



Now finding the coordinates of given square PQRS is
Then using Distance formula we get,
For
:

.................(1)
:

±
units
:

:

±
units
Solving equation (1) we found
Hence Possible coordinates of square PQRS is

And many more sets of coordinates are possible.
