I think you can only say that the width of the quadrilateral will be 5.

OH no it will be a rectangle and the length will be 1/2 * 20 = 10

so the perimeter is 2*5 + 2*10 = 30 <---- answer

Answer: The length of the second arc is 12 feet.

Step-by-step explanation:

Since we know that

A rope is swinging in such a way that the length of the arc is decreasing geometrically,

Length of first arc = 18 feet

Length of third arc = 8 feet

Let the length of second arc be x

As we know that

$\frac{a_2}{a_1}=\frac{a_3}{a_2}\\\\\frac{x}{18}=\frac{8}{x}\\\\x^2=18\times 8\\\\x^2=144\\\\x=\sqrt{144}\\\\x=12$

Hence, the length of the second arc is 12 feet.
