You don't. Perimeter is a concept associated with plane figures, not solid shapes.
the area and perimeter of the plane figures are square ,rectangle
Perimeter = sum of the lengths of the sides.
Can be any shape It is the edge of something So perimeter of a property can be round or square or irregular

You break it up into smaller shapes which are less irregular. If these are more regular, you can calculate their contribution to the perimeter, and their area. You can then add these together.
They are the result of combining shapes, either by adding parts or taking parts away. We calculate the perimeter of composite shapes by splitting them into simpler pieces and then calculating the perimeter of those simpler pieces.
the area and perimeter of the plane figures are square ,rectangle
The perimeter of the irregular shape is equal to the sum of the six segment around the outside of the figure. 1. Select the endpoints of the segment to be measured. 2. Measure distance. 3. Use the measure calculate feature of Geometer's Sketchpad to add the distance.
calculate the perimeter of 45.6m?
Perimeter = sum of the lengths of the sides.
an irregular figure is when it is open or have curved lines.
yes u can calculate the perimeter of a trapezium
The perimeter of a figure is the sum of its lengths around it.
If the figure is irregular, you can't calculate its area (for example) with some simple formula. You need to use integration - which basically means to divide the figure into many narrow strips, which you assume to be rectangles.
