calculate the length of each side then add them all up same with any 2d shape

The perimeter of a shape such as a polygon is the sum of its sides.

The perimeter of a polygon is the distance around the outside of the polygon. A polygon is 2-dimensional; however, perimeter is 1-dimensional and is measured in linear units.To find the perimeter of a polygon, take the sum of the length of each side.

Adding the lengths of the straight sides of any polygon will give its perimeter. In the case of regular polygons it will be the length of the side multiplied by the number of sides. But in the case of a non-regular polygon all the individual sides' lengths will be added to give you the perimeter.

Finding the perimeter of a polygon is finding how far it is in total along all the edges of the polygon; whereas finding the area of a polygon is finding how much space the polygon covers. The perimeter of a polygon forms the boundary around the area of the polygon.

The sum of the lengths of the sides of a polygon is called the perimeter.

Divide the perimeter by 4, to get the length of one side. From there, you can easily calculate the area.

Add the length of all sides. A regular polygon is a polygon where all sides and angles are congruent, so a shortcut is to know the length of one side and multiply it by the number of sides.

add the sides of the polygon.

If you restrict yourself to integers, the perimeter of a four-sided polygon is 16.

Even if you knew how many sides the polygon has, you stillcould not calculate its perimeter with that much information.Examples:-- An equilateral triangle with area of 20 has perimeter of 20.3885 .-- A square with area of 20 has perimeter of 17.889(rounded).-- A rectangle with area of 20 can have any perimeter more than 17.889 .4 by 5 . . . . area = 20, perimeter = 182 by 10 . . . area = 20, perimeter = 241 by 20 . . . area = 20, perimeter = 42..etc.

Any type of polygon can have a perimeter of 16 cm. There is no special name for polygons whose perimeter is 16 cm.
