Answer:

Approximately 17.4

Step-by-step explanation:

First you can start off by using the distance formula to find the sides.

EH = [tex]\sqrt{(-1-1)^2+(5-1)^2} =\sqrt{4+16}=2\sqrt{5}[/tex]

EF = [tex]\sqrt{(-1-2)^2+(5-8)^2}=\sqrt{9+9}=3\sqrt{2}[/tex]

The perimeter is [tex]4\sqrt{5}+6\sqrt{2}[/tex]

Which is 17.42955328

Approximately 17.4
