How to find the perimeter of a quadrilateral

It's the same as any other shape. Find the lengths of the sides and add them up.

To find the perimeter of a quadrilateral you would add the lengths of each  side together.

Example:

The perimeter is the sum or all the lengths.

If there was a rectangle with a length of 5 cm and a width of 3 cm.

To work this out you would first multiply 5 by 2, which is 10. Then you would multiplying 3 by 2, which is 6. Then you would add 6 and 10, which is 16.

1) Multiply 5 By  2.

2) Multiply 3 by 2.

3) Add 10 and 6.

About $17.16

Step-by-step explanation:

$80-$28.50= 51.5

Then you divide that by 3 (for the 3 ties)
