You can put this solution on YOUR website!
Let's see. Perimeter is the distance around the plane.
So, we just add the sides:
+%284x+%2B+1%29+%2B+%287x+-+2%29+%2B+%287x+%2B+1%29+
And we combine like terms:
+%284x+%2B+7x+%2B+7x%29+%2B+%281+%2B+%28-2%29+%2B+1%29+
And add:
+18x+%2B+0+
Remove the zero:
+18x+
And there's your final answer!
Power up!
