Answer:
Step-by-step explanation:
Given
---- the perimeter of fencing
Required
The maximum area
Let
So, we have:
This gives:
Divide by 2
Make L the subject
The area (A) of the fence is:
Substitute
Open bracket
Differentiate with respect to W
Set to 0
Solve for 2W
Solve for W
Recall that:
So, the maximum area is:
