The perimeter of the square patio is the sum of its side lengths
The length of the patio is: 8x + 2
The given parameters are:


The perimeter of a square is:

So, we have:

Divide both sides by 4

Hence, the length of the patio is: 8x + 2

By definition, the arc length is given by:
arc = R * theta * ((2 * pi) / 360)
Where,
theta: angle in degrees
R: radio
We have then:
(Arc) QPT if <QZT = 120:
theta = 360-120 = 240 degrees
R = 13.5 units
Substituting values we have:
(Arc) QPT = R * theta * ((2 * pi) / 360)
(Arc) QPT = (13.5) * (240) * ((2 * pi) / 360)
(Arc) QPT = 56.55 units
Answer:
(Arc) QPT = 56.55 units
