The area of the pentagon, rounded to the nearest tenth will be 32.7 square cm. Then the correct option is C.
<h3>What is a polygon?</h3>
The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
A regular pentagon has an apothem measuring 3 cm and a perimeter of 21.8 cm.
Then the side length of the pentagon will be
5 x Side length = 21.8 cm
Side length = 4.36 cm
Then the area of the pentagon, rounded to the nearest tenth will be
Area of pentagon = 5 x area of triangle
Area of pentagon = 5 x 1/2 x 4.36 x 3
Area of pentagon = 32.7 square cm
Thus, the correct option is C.

Answer:
negative
Step-by-step explanation:
A line sloping upwards from left to right has a positive slope
A line sloping downwards from left to right has a negative slope
The line here is sloping downwards from left to right.
Thus has a negative slope
