\noindent {\bf Problem statement} a) Compute the area of the bounded
region enclosed by the curve $y=e^{x}$, the line $y=12$, and the
$y$-axis. 

\medskip 

\noindent b) How does this area compare with the value of
the integral $\int_1^{12}\ln x\,dx$? Explain your answer. (A picture
may be helpful.)
