Answer:
[tex]9t^3+t^2[/tex]
Step-by-step explanation:
We are given a figure of a polygon with mentioned side lengths and we are to find the perimeter of it.
For that, we will simply add the given side lengths and simplify them.
Perimeter of polygon = [tex] ( 4 t ^ 3 - 5 ) + ( 4 t ^ 3 - 5 ) + ( t ^ 2 + 9 ) + ( t ^ 2 + 1 2 ) + ( t ^ 3 - t ^ 2 - 1 1 ) [/tex]
= [tex] 4 t ^ 3 + 4 t ^ 3 + t ^ 3 + t ^ 2 - t ^ 2 + t ^ 2 - 5 - 5 + 9 - 1 1 + 1 2 [/tex]
Perimeter of polygon = [tex]9t^3+t^2[/tex]
