# How do u find a perimeter?

i 4got how 2

Relevance

perimeter is the distance around something. so the perimeter of a square would be the combined lengths of all four sides.

If a square has a side of 4ft then its perimeter would be 16.

To get the perimeter of a rectangle, one only needs to know the length of one side and the width of one side of the rectangle. Thus the formula for the perimeter of a rectangle would be:

Perimeter = 2 times the length plus two times the width

P=2L + 2W

or Perimeter = 2 times the length plus the width.

P = 2(L+W)

Hopes this helps.

add up the length of all the sides

It will always be like this for any type of shapes. It gets different on how you find the other things of a shape. If you wanna know more info about it, google it.

P= L+L+W+W (L=length W=width P = perimeter)

Just add up all the sides

Perimeter of rectangle- 2(length + width)

Perimeter of a triangle- add up all the sides

all u gotta do is add up the measurements of the sides of the shape up like if a rectangle had 2 sides of 3 inches and 2 more sides of 5 inches add the 4 sides together e mail me if u need more help.!

Source(s): im an architect and u need to know the math

L+L+W+W L=length W=width Just add up all the sides

If you're talking about the perimeter of an object etc, you just add up all the sides (eg. all four sides of a square)

a perimeter is the length around a shape

for a rectangle it is length + width + length + width

for a circle it is pi * diameter or 3.14 * diameter

for a square it is 4 * length
