Step-by-step explanation:
A fence for a rectangular garden with one side against an existing wall is constructed by using 60 feet of fencing.
Perimeter of rectangle (3 sides)= 60 feet
Let 'x' be the width of the wall
Formula for the area of the rectangle is
Replace the length we got using perimeter
To find out the maximum are we take derivative
find out second derivative to check whether x=15 is maximum
second derivative is negative
So, Maximum area at x=15
To find maximum area we plug in 15 for x in A(x)
So, maximum area is 225 square feet
