The perimeter of the figure below is 163.7m. Find the length of the missing side.

Answer: 10.3 m
Step-by-step explanation: 163.7-(11.3x8)-11-(26x2), perhaps there is another way to solve the question, but this is the most straightforward method.
Answer:
10.3m
Step-by-step explanation:
The perimeter is the sum of all the side lengths.
To find the missing length you can write this equation and solve for x:
(1) 26 + 11.3 + 11.3 + 11.3 + 11.3 +11 +11.3 + 11.3 + 11.3 + 11.3 +26 + x = 163.7
(2) 153.4 +x = 163.7
(3) x = 10.3
Therefore, the missing length is 10.3m.
