Answer:
<u>Perimeter
</u>
![\bf \boxed{7+\sqrt{5}+\sqrt{8}+\sqrt{10}}](https://tex.z-dn.net/?f=%5Cbf%20%5Cboxed%7B7%2B%5Csqrt%7B5%7D%2B%5Csqrt%7B8%7D%2B%5Csqrt%7B10%7D%7D)
Step-by-step explanation:
Draw the polygon to have an idea of what you are being asked.
<h3>See picture attached
</h3>
Now find the length of each side and add them up, that is the perimeter.
To find the length of a side use the formula of the distance between to points (a,b) and (c,d)
<u>Distance between (-2,1) and (-3,3)
</u>
<u>Distance between (-3,3) and (-1,5)
</u>
<u>Distance between (-1,5) and (2,4)
</u>
<u>Distance between (2,4) and (2,1) (obviously 3)
</u>
<u>Distance between (2,1) and (-2,1) (obviously 4)
</u>
Add up all the lengths
<u>Perimeter
