Twelve is my guess. The question is unclear. A polygon does not have one "length".
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.
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.
A polygon with sides of equal length and equal angles is termed a regular polygon.
regular polygon\
It is a 4 sided quadrilateral polygon It has opposite parallel sides Its length is greater than its width Its area is length times width Its perimeter is the sum of its 4 sides It has 4 interior right angles that add up to 360 degrees It has 2 diagonals It will tessellate
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.
The perimeter of a polygon is the sum of the length of each of its sides. If the polygon is a regular polygon the you can calculate the perimeter as [number of sides] *[the length of one side]
Interior angles are equal and sides are equal in length and exterior angles add up to 360 degrees
Four sides of equal length. All four angles equal (90 degrees).
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.
A polygon with sides of equal length and equal angles is termed a regular polygon.
If the polygon has n sides, then the perimeter is 2.75*n metres.
Suppose the polygon has n sides. The polygon is regular => each of its exterior angles is equal.The sum of all n angles = 360 deg so each angle is 360/n deg Therefore 360/n = 40 => n = 9 sides. Then perimeter = 9 * length of one side = 63 ft. So each side is 63/9 = 7 ft.
Be there or be a 4 sided polygon of which the length of all the sides are equal, and the angles are 90 degrees.
The distance around a polygon is the length of its perimeter.

Polygon with four sides identical in length, four angles, all of which are 90 degrees.
