The given expression is
We extract the common factor 2x.
The first solution is 0.
Now, we solve the quadratic expression. We have to find two numbers whose product 20 and whose difference is 8. Those numbers are 10 and 2.
The Reuleaux triangle is shown in the attached figure
we know that
the area of a Reuleaux triangle is equal to
where
r=18.6/2--------> r=9.3 m
so
therefore
the answer is
