The perimeter of a rectangle is the sum of its sides, which are two widths and two lengths:

Since the length is twice the width, we have
, and the formula for the perimeter becomes

So, we have

Answer:
Step-by-step explanation:
From the previous answers you know the angles and side lengths of the triangle:
α = 60°
Ф = 30°
and the side lengths:
1,2 and √3.
Remember:
sin = opposite / hypotenuse
cos = adjacent / hypotenuse
tan = opposite / adjacent
Now you can read off from the triangle:
sin 30° = 1/2
cos 60° = 1/2
sin 60° = √3/2
cos 30° = √3/2
tan 30° = 1/√3
tan 60° = √3

Yea this is a Hamilton circuit. This is because it goes through A, C, E, B, D and return back to A without overlapping and successfully reaching each point.
