A perimeter is the sum of the lengths of all of the sides to a shape. Therefore, there is no actual number of sides a perimeter can have. A shape has sides. Its perimeter is just a number.
If rectangle, then 4 sides.
If pentagon, then 5 sides.
If hexagon, then 6 sides.
If triangle, then 3 sides.
If octagon, then 8 sides.
The perimeter of a dodecagon is the sum of the lengths of its 12 sides. These sides may be of different lengths.
The perimeter of a dodecagon is the sum of the lengths of its 12 sides. These sides may be of different lengths.
If there is regular polygon(having equal sides), then perimeter is L*N where L is length of side and N is no. of sides. If polygon is not regular then may Perimeter is equal to sum of all sides, if size of each side is known.
Add the lengths of the 3 sides to get the perimeter.
Perimeter is 5.
The sum of the lengths of the sides of a polygon is called the perimeter.
Hint: a square's perimeter is the sum of the length of its four sides...
add the sides toghther and then you'll have your perimeter of your triangle
Add all sides together to get the perimeter.
Perimeter = 6*6 = 36 cm
The perimeter of any pentagon is the sum of its 5 sides. So if a regular pentagon has sides that are 4 long, its perimeter is 20.
The perimeter is the sum of all of the sides of the figure. So, simply add up ALL the sides to discover what the perimeter is.
