I am trying to help my sister who is stuck on this problem for her alegbra class. Can someone show me how to do it so I know what I am talking about when I try to explain this to her. Thanks.

Problem reads:
A rancher has 20 miles of fencing to fence a rectangular piece of grazing land along a straight river. If no fence is required along the river and the sides perpendicular to the river are x miles long, find a formula for the area A(x) of the rectangle in terms of x. From practical considerations, what is the domain of the function A?
Thanks again!
