The vertices of a quadrilateral in the coordinate plans are known. how can the perimeter of the figure be found?

You can find the distance between each of the adjacent vertices and then add the results together.

Step-by-step explanation:

Perimeter is all of the side lengths added together, so if you can find the distances between each of the adjacent vertices and then add the together, it will be equivalent to adding all of the side lengths together.

the least common denominator is 40
