Answer:
Use the distance formula to find the length of each side, and then add the lengths.
Step-by-step explanation:
We are given the vertices of a quadrilateral in the coordinate plane.
We have to find the perimeter of the figure.
For doing so, we have to find the length of all the sides of a quadrilateral
The length of a line segment joining points (x1,y1) and (x2,y2) is given by the distance formula: 
after finding length of all the sides, we add the length of each side to get the perimeter.
Hence, the correct option is:
Use the distance formula to find the length of each side, and then add the lengths.
