Explanation:</h2>
We have the following system of three linear equations:
Let's use elimination method in order to get the solution of this system of equation, so let's solve this step by step.
Step 1: Multiply first equation by 
and add the result to the second equation. So we get:
Step 2: Multiply first equation by −2 and add the result to the third equation. So we get:
Step 3: Multiply second equation by −32 and add the result to the third equation. So we get:
Step 4: solve for z.
Step 5: solve for y.
Step 6: solve for x by substituting 
and 
into the first equation:

Answer:
5 m
Step-by-step explanation:
The perimeter is the sum of the lengths of the four sides. Opposite sides have the same length, so it is twice the sum of the lengths of adjacent sides.
The sum of adjacent sides is (32 m)/2 = 16 m. If one of them is 11 m long, the other is ...
16 m - 11 m = 5 m
The "missing" side is 5 m long.
