I REALLY need help on math because I can't understand what my teacher is saying in class.
Here's the question : Sixteen metres of fencing are available to enclose a rectangular garden.
a) represent the area of the garden as a function of the legnth of one side.
b) graph the function
c) what dimensions provide an area greater than 12 m ^2?
Please help me learn how to do this.
I'd appreciate it! =D
