The vertices of a quadrilateral in the coordinate plane are known. How can the perimeter of the figure be found?
AlekseyPX

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:  \sqrt{(x2-x1)^2+(y2-y1)^2}

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.
