Answer:
43.5 meters
Step-by-step explanation:
Area of regular hexagon =

in the problem you have a = 10 meters
and p = apothem = 8.7 meters
so if you apply the formula
you will have
area =( 1/2) × 10 × 8.7
area = 43.5 meters
Assuming you meant square root of 90 it would be
90 equals 3 times the square root of 10
√90 = 3√10
Answer:

Step-by-step explanation:
Area of a square = 
If l =
,
Then area =

For
to be conservative, we need to have



Integrate the first PDE with respect to
:

Differentiate with respect to
:

Now differentiate
with respect to
:

So we have

so
is indeed conservative.
