If given the total perimeter only it is impossible to do.
However, if the lengths of each part of the perimeter are given (or can be worked out from the lengths given) then split the shape's area up into areas of shapes whose area you do know how to calculate, calculate each area and add them up.
For example if you have a hexagonal L shape with lengths 1cm, 3cm, 3cm, 1cm, 4cm, 4cm, (all angles 90o) it can be split into two rectangular areas, one of 1cm x 3cm (from the top of the back of the L to the top of the piece across the bottom) and the other of 4cm x 1cm (all the way across the bottom of the L).

In general you cannot find the perimeter of any shape if only the area is given.
It depends on the shape.
More information is required in order to answer this question. What is the shape for which the perimeter is given? If it anything other than a circle or regular polygon it is not possible to determine the area. For a circle or regular polygon, the answer will depend on the shape.
There is insufficient information to answer the question. For a given area, the perimeter depends upon the shape. For a given area, the circle will have the smallest perimeter. For polygons, regular polygons will have a smaller perimeter than an irregular one of the same area. Also, for regular polygons, the greater the number of sides, the smaller the perimeter.
Most shapes can have the same area and different perimeters. For example the right size square and circle will have the same are but they will have different perimeters. You can draw an infinite number of triangles with the same area but different perimeters. This is before we think about all the other shapes out there.
