A book designer decided that the pages of a book should have 1in. margins at the top and bottom and 1/2 in. margins on the sides. She further stipulated that each page should have an area of 60 in.2. Find a function in the variable x, giving the area of the printed region.

If x is the page width,
we know the height is 60/x
a = (x1)(60/x  2)
