Find the dimensions of a rectangular flower garden with a maximum area that can be enclosed by a 100 m fence. What is the maximum area?
Let L and W be the dimensions:
Given: Area = at maximum , P = 100 m
We know that P = 2(L+W) , thus
so ,
Then Area = LW , therefore
Get the derivative using power rule:
Then equate the derivative to 0
Now that we get the value of W , we will find the value of L
Henceforth , the dimensions are 25 meters by 25 meters
Lastly , we will solve for the maximum area
Therefore , the maximum area measures 625m²
