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.
A polygon with sides of equal length and equal angles is termed a regular polygon.
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.
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).
A polygon with sides of equal length and equal angles is termed a regular polygon.
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.
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.
regular polygon\
Polygon with four sides identical in length, four angles, all of which are 90 degrees.
