Hello from MrBillDoesMath!

  Perimeter = 17x + 4

Discussion:

(So you are trying to sneak #2 out of me too );

Perimeter = sum of lengths of sides. Starting at the bottom of the figure and proceeding counterclockwise.

Perimeter =  (3x +2) + (3x+2) + (4x-1) + (4x-1) + (3x + 2) .

Separate and combine x's and constants:

Perimeter = (3x + 3x+4x+4x+3x) + (2 + 2 -1 -1 + 2) =

                = 17x + 4

You answer has the wrong constant value ( you wrote 17x + 1. The constant should be 4)

Thank you,

MrB
