The missing length of the missing side is x+1.
To find the perimeter of this object, we need to know hat perimeter truly means.
Perimeter-The sum of all the sides.
The sides from the trapezoid are 3x+1, x , and x.
We combine like terms, so 3x + x + x = 5x
1 is the only number.
We are left off with 5x+1. Our objective is to get 6x+2.
How do we get there? We add 1x or x (1x and x) are the same thing, and we add one.
5x+1 + 1x + 1 = 6x+2;
Therefore the renaming length of the missing side is 1x+1.
