Hint: BC and AD are the parallel sides and have lengths of: 8 - 2, or 6 units, and 8 - - 2, or 10 units, respectively
Additionally, CD is a vertical line that's parallel to the y-axis, and has a length of: 3 - - 2, or 5 units
All you need to do now is find the length of the other non-parallel side (AB) using the distance formula: 
Then add the 4 sides to get the perimeter.
