You find the perimeter of a triangle by adding all the sides. There is no special rule for finding the perimeter.
It depends how big it is. But the rule is: Side length x 8 = Perimeter. For example, if one side was eleven centimeters long then the perimeter would be P= 11 x 8. It would be eighty-eight centimeters. Note: This rule only works for regular octagons. If you need to find the perimeter of an irregular octagon, then you have to measure each side and add up the measurements of each side.

You find the perimeter of a triangle by adding all the sides. There is no special rule for finding the perimeter.
There is no rule for the perimeter of an acute triangle. You simply need to add the sides.
area of parallelogram= base*height perimeter= 2(length+breadth)
Perimeter is the distance around something. In the case of a polygon, you add up the lengths of all the sides.
s=side length P=perimeter P=4s
Simple, Add all the sides of the shape up.
The perimeter of a rectangle is found by the following formula: (Length x 2) + (Width x 2) or Length + Length + Width + Width.
It depends how big it is. But the rule is: Side length x 8 = Perimeter. For example, if one side was eleven centimeters long then the perimeter would be P= 11 x 8. It would be eighty-eight centimeters. Note: This rule only works for regular octagons. If you need to find the perimeter of an irregular octagon, then you have to measure each side and add up the measurements of each side.
Perimeter = The sum of the lengths of each side. There may be special rules applicable to selected shapes, but the above is the only general rule - in answer to the general question.
2 x (l + w)or 2l + 2w
Perimeter of the base of the ruler multiplied by its height
