(a)
Explanation:
As width of page is
top and bottom margins are
the dimensions of print area are
and as print area is
(a) Hence area of page
(b) We ought to have
(c) The graph of area vs.
graph{(30x)/(x-4)+2x [-5, 25, 43.32, 83.32]}
and area is minimum at around
Using calculus given
and this is zero when
