You don't but it makes no difference if you do because a corner has no length.
If you're trying to measure the perimeter of almost any shape like a square or triangle or octagon, simply count all the unit measurements of each side and add them together. If the unit your measuring is unknown, then leave it as units. For example, if you were finding the perimeter of a rectangle that has the measurements 6units, 6units, 4units, and 4units, the perimeter would be 20units. I hope this helped :)
Cuboid has : 8 corners (vertices) 12 edges
kilometer is 1000 times a meter for a perimeter
The perimeter of a 340-acre square lot is 2.92 miles.
we know,perimeter of rectangle = 2 * ( l+b) perimeter= 2 *(45+30) = 2 * 75 =150 cm

No.
count the corners
Count them.Count them.Count them.Count them.
no that's perimeter
the vertices are the corners to the shape, so you count the corners to whatever shape.
All plane figures except circles have corners, and even that is debatable that circles have an infinite number of corners. Corners are simply where the line tracing the perimeter of the shape changes direction. Without any corners, you would have not have a convex figure. You would have a line. ■
That's because "perimeter" means the distance around something - not the spaces inside. If you count squares inside a figure, you are finding the AREA, not the PERIMETER.
Circle = Circumferance. Triangle = Perimeter. Perimeter for a Triangle, you count up the number of units on it.
If you count all the corners (vertices), That is five!
Thinking about the two dimensional equivalent, sharp corners basically waste perimeter while encompassing little additional area. As you increase the number of corners in a shape, you end up carving out more area for the same input of perimeter. As a shape's number of sides approaches larger and larger numbers, it rounds out to the point where you can think of a circle as a shape with infinite number of sides and corners. The same goes for three dimensional figures, substituting volume for area. Essentially, sharp corners are wasteful, the more corners you have the less wasteful they are, so if you have an infinite number of corners, you'll be enclosing the most volume/area with minimum surface area/perimeter.
