In this polygon, all angles are right angles.

The area of the given polygon is 1830 cm².

<h3>What is a polygon?</h3>

A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.

Each line of the polygonal circuit's segments is referred to as its edges or sides.

We know the area of a square is (side)² and the area of a rectangle is (length×width).

From the given diagram we can think of this polygon as a square having a side length of 46cm and a rectangle having a width (30 - 14) = 16cm and length 21cm, And subtract the area of the rectangle from the area of the square which is,

= (46×46) cm² - (16×21) cm².

= (2166 - 336) cm².

= 1830 cm².

8(3n + 5) = -32 what does n =

olga_2 [115]

Answer: n = -3

Step-by-step explanation:

8(3n + 5) = -32

Divide both sides by 8.

(3n + 5) = -4

Subtract 5 by both sides.

3n = -4 - 5

3n = -9

Divide both sides by 3.

n = -3

arlik [135]

Answer:

A public communications director would make $1,196,800 over a period of 20 years.

Step-by-step explanation:

The median salary of an engineer is $73,400 per year.

Piper has researched that a public communications director makes $13,560 less than this. (so we need to take this amount from the salary of an engineer)

Therefore, we would have that a public communications director would make

73,400 - 13,560 = $59, 840 per year

Now, the problem asks us how much a public communications director will make over a period of 20 years, thus, we have to multiply the amount she will get per year by 20.

Thus, over 20 years she would make: 59,840 x 20 = $1,196,800
