Answer:
Perimeter = 120m
Step-by-step explanation:
The given function is that is a cubic polynomial

when arranged in descending order that is from highest degree to lowest degree

Since it is a three degree polynomial it has three roots.
According to rational root theorem , the possible roots of the above expression that is factors of
=
are 
As you can see from the graph all roots of this polynomial are real.
The smallest positive root is 0.954 and smallest negative root are -0.724.
