Lol, were are learning the same thing! Anyway, Your answer would be 292.5. It would be this answer because the dotted lines are actually pointing out what the height is and the area of a triangle equals 1/2bh(base x height divided by 2). So knowing this information, you would multiply 13 x 45 and get an answer of 585. Then you would divide it by 2. This leads you back to the original answer of 292.5. I hope I helped! :)

If N = 9 ft, Q = 2 ft, R = 4 ft, S = 9 ft, and T = 3 ft, what is the perimeter of the object?
lana66690 [7]

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.

You need to create a fenced off region of land for cattle to graze. The grazing area must be a total of 500 square feet, surroun
KATRIN_1 [288]
<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
