Total perimeter of the pentagon can be calculated by adding the length of the sides.
Perimeter = d1+d2+d3+d4+d5
Distances between coordinate is computed using the distance formula.
d 1= sqrt(-2+2)^2+(3+2)^2
d1 =5
d2 = sqrt(2+2)^2+(4-3)^2
d2= sqrt17=4.1
d3= sqrt(3-2)^2+(1-4)^2
d3=sqrt10=3.2
d4=sqrt(0-3)^2+(-2-1)^2
d4=sqrt18=4.2
d5=sqrt(-2-0)^2+(-2+2)^2
d5= 2
Perimeter of the pentagon = 5+4.1+3.2+4.2+2
                                              = 18.5
