Answer:
<h2>440 square units</h2>
Step-by-step explanation:
We can find half of a side of the pentagon with the expression
Because, as a regular polygon, all its sectors have the same central angle, and the apothem divides equally each sector in two equal parts.
Therefore, half of a side is 8 units long, which means each side measures 16 units.
Now, the area of a penthagon is defined by
Where 
is the perimeter and 
is the apothem. Where the perimeter is the sum of all sides, which is 80 units.
Therefore, the right answer is the second choice.

Answer:
$ 125,000
Step-by-step explanation:
Given,
The amount of rent = $ 25,000,
The salary of assistant = $ 30, 000
Expenses = $ 20,000,
Also, her best alternative is to work elsewhere and to earn a salary of $50,000 per year.
Thus, the investment in the firm = 25000 + 30000 + 20000 + 50000
= $ 125,000,
Now, if she earns zero economic profit,
Then her revenue = investment
= $ 125,000
