Need help finding the perimeter/area, or length of the missing side for each polygon
My problems:

#16 says P = 19''

Maybe to start, helping me with #16, #17, and#18

First, what do you mean by "#1" ??

Second, with which do you need help?

Hi!
I guess that p=19 beacuase i cant see the whole paper..

if p=19 this means that: 4+4+3+3+x=19
8+6+x=19
14+x=19
14+x-14=19-14
x=5

x is unknown so we need to find the perimeter by add all the sides together and solve for x :)

Try the other ones yourself by adding in #17 and sovle for x in #18 :)

Good Luck!

Hello murze,
If you are still looking for help I suggest that you prepare a list of areas and perimeters of the figures in the questions.Then show your work on one which is stumping you.
