(-2,-2),(3,-3) ....distance = sqrt 26 = 5.099
(3,-3),(4,-6)......distance = sqrt 10 = 3.162
(4,-6),(1,-6)......distance = sqrt 9 = 3
(1,-6),(2,-4).....distance = sqrt 5 = 2.236
(-2,-4),(-2,-2)...distance = sqrt 20 = 4.472
perimeter is all the sides added together....... = 17.969 = 17.9 units
** I used a distance formula calculator to calculate the distances between each point....just to let u know how I did this
