Side 1: x+3
Side 2: x+6
Side 3: x^2-2x
Side 4: 2x-2
P=perimeter=31cm
The perimeter is the sum of the sides:

Subtract 31cm from each side

or
or
The value of x is 4
Side 1: x+3=4+3=7 Side 1 is 7 centimeters.
Side 2: x+6=4+6=10 Side 2 is 10 centimeters.
Side 3: x^2-2x=16-8=8 Side 3 is 8 centimeters
Side 4: 2x-2=8-2=6 Side 4 is 6 centimeters.
CHECK:
P=(Side 1)+(Side 2)+(Side 3)+(Side 4)
31cm=(7cm)+(10cm)+(8cm)+(6cm)
31cm=31cm
