Answer:

23x + 9

Step-by-step explanation:

Perimeter = 2*(length + width)

     = 2*( 5.5x + 10 + 6x - 5.5)

     = 2* (5.5x + 6x + 10 - 5.5)         {Combine like terms}

5.5x and 6 are like terms  & 10 and (-5.5) are like terms

        = 2* (11.5x + 4.5)

        = 2*11.5x + 2*4.5

        = 23x + 9
