Answer:
The answer is probably 85.
Step-by-step explanation:
Because we aren't multiplying we would all the sides.
20+10+7.5+7.5+45+8+27= 85
I added 27 because you have to add all sides. How I got is in the picture. Why did I add 10 and 8 because those are also part of the width. And I also added 10 and 8. This is called perimeter when you add sides.
Hope it helps!
