The area of rectangle is equal to
-----> equation B
substitute equation A in equation B

This is a vertical parabola open downward
The vertex is a maximum
The y-coordinate of the vertex of the graph is the maximum area of the garden and the x-coordinate is the length for the maximum area
using a graphing tool
The vertex is the point 
see the attached figure
Find the value of y
-----> 
The dimensions of the rectangular garden is
by 
For a maximum area the garden is a square
The maximum area is
