The coordinates of the vertices of a polygon are (−2, −2) , (−2, 3) , (2, 4) , (3, 1) , and (0,−2) . What is the perimeter of the polygon?

Use the distance formula between points

 

For instance

 

Distance   (-2,3) to  (2, 4)  = 

 

sqrt [ (-2 -2)^2 + (4 - 3)^2 ]  =  sqrt ( 16 + 1 )   sqrt (17 )  ≈  4.1231

 

Here's a pic of all the sides with their lengths :

 

 

I'll let you finish the math.....!!!!
