(c) Maximum area
square meters
Step-by-step explanation:
(a)
Given:
Total length for fencing = 160 m
Width of the rectangle =
m.
Let the other length of the rectangle be
m.
Then, from the figure,

Now, area of a rectangle is equal to the product of its length and width.
So, area is, 
(b)
Given:

For maximum area, derivative of area with respect to
must be 0.
So, 
Therefore, for maximum area,
.
(c)
Given:

Maximum area occurs at
. Plug in 40 for
in
expression. This gives,
Maximum area is,

Therefore, maximum area is 3200 square meters.

Step-by-step explanation:
Multiplying the inequality by 2 will eliminate the fraction and give you ...
x ≤ 36
The "or equal to" part of the symbol means the end dot will be solid. The "less than" part of the symbol means the graph is shaded to the left of the end dot, which is at x=36. This description matches the graph shown below.
