Irregular objects can have their perimeters measured in a variety of different ways. Probably the easiest is to run a string along the edge of the object and then later lay the string flat and measure it. Another way is to measure in partial straight segments and approximate.
If you wanted to describe the length and breadth of an irregular shape you would find the maximum length and breadth. You could sandwich the object between two flat boards, and measure the distance between the boards. Then rotate the object 90o and do it again, for the breadth.
If the object is irregular the best way is to measure the volume of water it displaces when you immerse it completely in water.
I would place it in a container full of liquid after measuring the liquid. I would measure the amount of liquid displaced by the object. That amount is equal to the volume of the irregular object if it is fully submerged in the liquid.
You need to measure the length of each line segment or arc and then sum them.
Use the water displacement method. The object is equal to the amount of water it displaces. :)

Displacement
to measure an irregular object you fill a graduated cylinder part way with water, measure that in milliliters, put the object in, measure that in milliliters, then subtract the 1st measurement from the 2nd and convert the answer to cubic centimeters. 1 milliliter =1cubic centimeter

it can be found by first taking the volume of the water itself and then the volume of the object in the water. you pour water into the 12-sided object, then measure the amount of water using the graduated cylinder. Then you do this: length x width x height = volume
use a ruler to measure the lenght of each side of the object
To do this, you will need to measure the length and the width and the height and your have your answer to the volume.
You don't measure with length. You measure the length of an object with a ruler. You would use inches or metres as your units.

A pentagon can be regular. But, if one of its sides is of a different length, or one of its angles is of a different measure then it is irregular.
Push it down, and measure how much water is displaced.
