A farmer needs to enclose a field with a fence. She has 10 meters of fencing material. Determine the dimensions of the field that will enclose the largest and smallest areas.

Instructions:[br][list][*]Drag the purple 'X' or use the 'Show Animation' and 'Stop Animation' Buttons to change the dimensions of the field.[br][*]Click the check box 'Show Area' to show or hide the calculated area. [/list][br][br][i]Make a Prediction[/i]: Determine the dimensions of the field that will enclose the largest area. What shape is this field?[br][list][*]Check your predictions by changing the dimensions of the field until the calculated area is the greatest.[/list][br][i]Make a Prediction[/i]: Determine the dimensions of the field that will enclose the smallest area.
