Answer:

About 72.23 metres

Step-by-step explanation:

Use Pythagorean Theorem to figure out all of the missing sides and then add them up. There are four right triangles you can do this with.

For the second triangle, the base is eight plus three. Also, for the first triangle, there is another triangle that has the exact same measurement so that's why I added 20 with 20. The perimeter is 175 m
Hope this helps :)
