Before you answer, make sure to do a step by step explanation, if you forget, it's whatever. I'll give crowns to the people that do step by step, and leave a 'thanks' for the answer only.

Answer:
The answer would be 56 m
Step-by-step explanation:
First find the bottom length of the shape by adding 5 and 11, bc the 11 is only part of the bottom length, and 5 is the other part: 5+11=16
now add all the side lengths together: 5+5+5+7+7+11+16=56
