    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

    Hi!
    Lets start with #16.
    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.
