Answer:
I think the coordnates are incorrect because they do not make a pentagon when graphed. Could you please check and make sure those are right.
Explanation:
But to do the question, you graph the points and then use the distance formula to find the side lengh of each side. Then simply just add them together. Also if you don't want to draw out a coordnate plane, you can use Desmos, an online graphing calculator.
