<u>Sum of interior angles of a polygon:</u>
- (n - 2)180 = 160n
- 180n - 360 = 160n

First, notice that the term
doesn't have any l terms in it, so we can just move this to the left side by subtracting both sides by
:
A -
= 2lw
Now, the right side has 2lw, so we must divide both sides by 2w to isolate l:

Answer:
p = 9
Step-by-step explanation:
8(8p + 8) = 640
use the dist property
64p + 64 = 640
<u> -64 -64</u>
64p = 576
divide by 64
p = 9
