When looking for a perimeter we are actually looking for a distance, so we can use the look at this problem in parts.
The distance between each point can be found by using the formula:
d=sqrt%28%28X-x1%29%5E2%2B%28Y-y1%29%5E2%29
distance1= d=sqrt%28%28-5-7%29%5E2%2B%28-3-2%29%5E2%29=13
distance2 =d=sqrt%28%28-5-4%29%5E2%2B%28-3-6%29%5E2%29=12.7279
distance3=d=sqrt%28%287-4%29%5E2%2B%282-6%29%5E2%29=5
the perimeter = 13+12.7279+5 = 30.7279
