I don’t have enough information to find the perimeter — the side lengths or a diagram are missing. Could you either

- paste the full problem text including any side labels/expressions, or
- upload the figure (or give the lengths of AB, BC, CD, DA)?

If you want the general procedure: the perimeter P of quadrilateral ABCD is
P = AB + BC + CD + DA.
If the sides are given as algebraic expressions, add those four expressions and simplify. If there are relationships (parallel sides equal, or right triangles giving lengths), tell me those and I’ll compute the numeric/simplified answer.
