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

Assistance needed.

Please type your subject in the School Subject box. Any other words are likely to delay responses from a teacher who knows that subject well.
