Find out the length of each side. For the slanty sides, you can do this by using the formula

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

For the straight sides (like the one on the bottom and the one on the left), just use simple subtraction.

Add up all 4 sides and you get the perimeter. You should get 20, 15, $5\sqrt{5}$ and $5\sqrt{26}$ . The total is 35 + $5(\sqrt{26} +\sqrt{5} )$ .
