Perimeter: Perimeter is the distance around a two-dimensional shape, a measurement of the distance around something.
So, first lets see what sides that are clear to us:
-->3x+6
-->6x+8
-->x+4
-->3
-->2x+2
-->6x+5
In this case, all of the sides are labeled clearly, so all we have to do is aff them toghther
3x+6+6x+8+x+4+3+2x+2+6x+5
Combine like terms
Therefore it is: 18x+28
