Evaluate the Area of the Region

$$f(x,y)=3e^{-y};

R=\biggr[(x,y):0 \le x \le 8, 0 \le y \le \ln 4\biggr]$$

\begin{align*}\displaystyle

I&=\iint\limits_{R} f(x,y) \quad dx \, dy \\

&=\int_{0}^{8}\int_{0}^{\ln 4} 3e^{-y} \quad dx \, dy \\

\end{align*}

ok just seeing if this is setup ok before proceed.

since there is no
