We would be needing you to tell us how the "triangle park shown" actually looks like...
Subtract both the expressions that are written on the two known sides from the total perimeter and you will find out the missing side. Makes sense, right?

e.g. one side is 2x+%2B+1 and the other is x-3.
To find the third side you do %2811x-5%29+-+%28%282x%2B1%29+%2B+%28x-3%29%29
=11x-5+-+%283x-2%29 = 8x-3
