Question

Please help:Find the perimeter of parallelogram EFGH to the nearest tenth.

Answer 1

Answer:

Approximately 17.4

Step-by-step explanation:

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

EH = $\sqrt{(-1-1)^2+(5-1)^2} =\sqrt{4+16}=2\sqrt{5}$

EF = $\sqrt{(-1-2)^2+(5-8)^2}=\sqrt{9+9}=3\sqrt{2}$

The perimeter is $4\sqrt{5}+6\sqrt{2}$

Which is 17.42955328

Approximately 17.4
