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.
200 x 9
900 x 2
600 x 3
450 x 4
360 x 5
300 x 6
225 x 8
Yes, because if you round 293 down to 290 and 44 to 40 290-40=250
