Question 913531
You need to know the side lengths AB, BC, CD, DE, AE


To find the side length of say AB, you find the distance from A to B. So you'll use the distance formula. I'll show you how to find the distance from A to B


*[invoke distance_formula -6,2,-4,7]


So the distance from A to B is roughly 5.3851648071345 units.


That means AB is approximately 5.3851648071345 units long.

You'd use the same formula and same basic steps to find the other side lengths. You can use this <a href="http://www.algebra.com/algebra/homework/Length-and-distance/distance-formula.solver">distance formula solver</a> to help check your work.


Once you have all 5 side lengths, you add them all up to get the perimeter of the pentagon.


Let me know if you need more help or if you need me to explain a step in more detail.
