Find the perimeter of the polygon. Round your answer to the nearest tenth.

dimulka [17.4K]

The perimeter of the polygon is 26.1 units.

To find the perimeter of the polygon.

<h3>What is polygon?</h3>

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.

Given that:

Distance between points $(x_{1} ,y_{1} )$ , $(x_{2} ,y_{2} )$ is given by

$\sqrt{(x_{2} -x_{1} )^{2}+(y_{2} -y_{1} )^{2} }$

As per the graph,

point Q is (2,0)

point R is (4,5)

point S is (8,7)

point T is (6,4)

point U is (10,3)

QR= $\sqrt{(4 -2 )^{2}+(5 -0 )^{2} }=\sqrt{4+25} =\sqrt{29}$ $=5.38 units$

RS= $\sqrt{(8 -4 )^{2}+(7 -5 )^{2} }=\sqrt{16+4} =\sqrt{20}$ $=4.47 units$

ST= $\sqrt{(6 -8 )^{2}+(4 -7)^{2} }=\sqrt{4+9} =\sqrt{13}$ $=3.60 units$

TU= $\sqrt{(10 -6 )^{2}+(3 -4 )^{2} }=\sqrt{16+1} =\sqrt{17}$ $=4.12 units$

QU= $\sqrt{(10 -2 )^{2}+(3 -0 )^{2} }=\sqrt{64+9} =\sqrt{73}=8.54 units$

Perimeter refers to sum of lengths of all the sides.

Perimeter =5.38+4.47+3.60+4.12+8.54=26.1 units

So. the perimeter of the polygon is 26.1 units.

Answer correctly for brainleist and 5 mark

notsponge [240]

Answer:

It is the last answer.

Step-by-step explanation:

If you graph this, there will be no point more negative than (-4/3, -5).

This means the x and y values must be greater than or equal to these values, as the fourth answer will show.

The sales manager of a company awarded a total of \$3000$3000dollar sign, 3000 in bonuses to the most productive salespeople. th

lord [1]

Let number of $250 bonus = x

Let number of $750 bonus = 7

Given that total bonus amount awarded is $3000. So we can write equation:

250x+750y=3000

750y=3000-250x

$y=\frac{3000-250x}{750}$

$y=\frac{300-25x}{75}$

$y=\frac{12-x}{3}$

Given that both type of bonus awarded are at least one.

So that means y>1 and x>1

Now we have to find any one possible solution.

Number of awards can only be whole numbers so we can plug x=2,3,4,... to see which one satisfies above equation and gives x as whole number.

I found that x=3 is working good.

at x=3, we get:

$y=\frac{12-x}{3}$

$y=\frac{12-3}{3}$

$y=\frac{9}{3}$

y=3

Hence final answer is given by:

Number of $250 bonus = 3

and number of $750 bonus = 3
