Determine the perimeter of quadrilateral KLMN with vertices K(-4, 2), L(2, 2), M(8, -3), and N(-10, -6).

Question

anonymous · Answer

K
1. Find the distance of each line

anonymous · Answer

distance formula:
$$d=\sqrt{(x1-x2)^2+(y1-y2)^2}$$

anonymous · Answer

Lines us need to find: KL, LM, MN, KN.

anonymous · Answer

KL is easy, because the Ys are the same. You just need to find the difference between the X's
-4-2=-6
they are 6 spaces apart; KL=6

anonymous · Answer

u need to use the distance formula for the others.
LM:
$$distance of LM=\sqrt{(2-8)^2+(2--3)^2}$$

anonymous · Answer

$$d=\sqrt{(-6)^2+(5)^2}$$

anonymous · Answer

$$d=\sqrt{36+25}$$

anonymous · Answer

$$d=\sqrt{61}$$

anonymous · Answer

Do the same with the other sides, and add them all together. 
Hope this helped!
