find the least amount of fence needed?
The rectangular plot of ground containing 432ft^2 is to be fenced within a large plot.
Through graphing, approximate the dimensions of the plot that requires the least amount of fence.
i'm sure there is a way to solve this without graphing, but atm i dont understand how to solve it at all. any help is appreciated. :)

Take the square root of the total area, now make a square plot that has sides equal to that length (all four sides = 20.785').
This is because the maximum area to parameter rectangle is a square. A circular plot containing 432 ft^2 would have the smallest area, but if you must stick to rectangles the square is the best bet. You can prove this graphically, using algebra or calculus.
