The perimeter of the object NQRST will be 27 ft.
<h3>What is a regular figure and its perimeter?</h3>
A regular figure with n-sides has n equal sides in it, and they are the only parts of it(that means, nothing more than those equal lengthed n sides).
Suppose that length of each side of that figure be of u units, then we have the perimeter as: A + B + C + D units.
Its the sum of length of the sides used to made the given figure.
Given; If N = 9 ft, Q = 2 ft, R = 4 ft, S = 9 ft, and T = 3 ft, then we need to find the perimeter of the object.
So the perimeter of the object NQRST.
N + Q +R + S +T
= 9 + 2 +4 + 9 + 3
= 27 ft
Therefore, the perimeter of the object NQRST will be 27 ft.

<h3>Given</h3>
A regular polygon with area 500 ft² and apothem 10 ft
Cost of fence is $7.95 per ft
<h3>Find</h3>
Part III The cost of fence around an area scaled to 60 times the size
<h3>Solution</h3>
You don't want to think too much about this, because if you do, you find the regular polygon has 3.087 sides. The closest approximation, an equilateral triangle, will have an area of 519.6 ft² for an apothem of 10 ft.
For similar shapes of scale factor "s", the larger shape will have an area of s² times that of the smaller one. Here, it appears the area scale factor s² is 60, so the linear scale factor is
... s² = 60
... s = √60 ≈ 7.7460
The perimeter fence of the 500 ft² area is presumed to be 100 ft long (twice the area of the polygon divided by the apothem—found in Part I), so the perimeter fence of the industrial farm is ...
... (100 ft)×7.7460 = 774.60 ft
and the cost to construct it is
... ($7.95/ft)×(774.60 ft) ≈ $6158
Y equals 4 hope i could help
Let me see if 57.3 is correct I’m not sure tho does it give you options?
