Answer:

The surface of the polygon is the total space or area that is limited by the borders of the polygon.

Step-by-step explanation:

This area is the amount of space limited by the borderlines and occupied by a polygon. By definition, the sides of the polygon are the same in size. The area of any polygon can be defined by dividing the polygon into triangles.

Answer: $277.91

<u>Step-by-step explanation:</u>

The average of the 2 highest salaried quarters is:

$\dfrac{\$13,500+\$12,775}{2}=\dfrac{\$26,275}{2}=\$3,137.50$

Divide that by 26 (weeks) to find out her average weekly salary:

$\dfrac{\$3,137.50}{26}=\$505.29$

Multiply that by 55% (0.55) to calculate her weekly unemployment benefit:

$\$505.29(0.55)=\$277.908$

Round to the nearest penny --> $277.91

Answer:

Part A)

$86=2(x+22)$

Part B)

$l=26\text{ cm}$

Step-by-step explanation:

We know that the rectangle has a length of (x+5) and a width of 12 cm.

Part A)

Remember the formula for the perimeter of a rectangle:

$P=2(l+w)$

We know that the perimeter is 86. Substitute that for P:

$86=2(l+w)$

Substitute (x+5) for the length l and 17 for w. So:

$86=2((x+5)+17)$

We can simplify this to acquire our equation:

$86=2(x+22)$

Part B)

To find the length, let's find our x first. We have the equation:

$86=2(x+22)$

Divide both sides by 2:

$43=x+22$

Now, subtract 22 from both sides. Therefore, our x is:

$x=21$

To find the length, remember that the length is:

$l=x+5$

Since we now know the value of x, substitute 21 for x:

$l=21+5$

Add:

$l=26\text{ cm}$

So, the length is 26 centimeters.

And we're done!
