Answer: 29
Step-by-step explanation:
I will explain how I got my answer and how it is correct. It is asking for the perimiter, so this is how you find it.
1. Add the lengths of all sides. (19 + 19 + 11 + 9 = 58)
2. (ONLY FOR TRIANGLES) Since this is a triangle, half that number because it is not a full square. (58 divided by 2 = 29)
Hope this helps! :)
