<u>FINAL ANSWER</u>

<u><em>In Decimal Form (Rounded to 3 significant figures)</em></u>
<em>x≈-1.24, 3.24</em>
Answer:
a) see below
b) 40x20 meters
Step-by-step explanation:
Write down what you know:
- The area of the enclosure is length*width, so

- The length of the fencing is 80 meters, so

Now we have to combine these two equations above, and get rid of y in the process.
First rewrite the second as:

Then substitute for y in the first:

b) To maximize A, find the zero of the first derivative:

So y = (80-40)/2 = 20 meters.
It would be 1,200,000 because the 9 is in the ten thousand place.
