Let me handle this. @sierra! :)
OpenStudy (sierra!):
that was for a parallelogram

@pielover123 The formula for the area of a polygon is \(\dfrac{1}{2}\) x apothem x perimeter.
OpenStudy (anonymous):
First, what is the apothem, and what is the perimeter?

Do you know what the apothem is?
OpenStudy (anonymous):
No
OpenStudy (anonymous):
The apothem is the line going to the middle of the polygon, do you see that?

yes
OpenStudy (anonymous):
Ok, so what is the value of the apothem, and what is the value of the perimeter?
OpenStudy (anonymous):
28.9 ?

Well, the perimeter is adding up all the sides, and since it has 7 sides of equal length, we can multiply 28.9 to get the perimeter.

*we can multiply 28.9 x 7 to get the perimeter

Good. Since we know the formula for the area of a polygon, we can first multiply \(\dfrac{1}{2}\) to the apothem. Can you do that?
OpenStudy (anonymous):

OpenStudy (anonymous):
No, not the perimeter, multiply \(\dfrac{1}{2}\) to the apothem...

Look at the polygon...What is the value of the apothem?
OpenStudy (anonymous):
28.9
OpenStudy (anonymous):
No, the apothem is the line going to the middle of the polygon
OpenStudy (anonymous):
oh ok it is 30

Yes, so multiply 1/2 x 30...
OpenStudy (anonymous):
ok 15
OpenStudy (anonymous):
Yes, and multiply 15 to 202.3 to get your answer.
OpenStudy (anonymous):
3034.5
OpenStudy (anonymous):
Yes, so that is your answer.
