Maxima and Minima help!! (1 Viewer)

[missgraceful]

A magazine advertisement is to contain 50cm^2 of lettering with clear margins of 4cm each at top and bottom and 2cm at each side. Find the overall dimensions if the total area of the advertisement is to be a minimum.

I really can't get this.
Any help would be much appreciated.
