Given Data:
The dimension of the rectangle is 9 times the original dimension i.e.
[tex]\frac{l_f}{l_i}=\frac{b_f}{b_i}=9[/tex]
The ratio of the area of the rectangle can be determined as,
[tex]\begin{gathered} \frac{A_f}{A_i}=(\frac{l_f}{l_i})^2 \\ =9^2 \\ =81. \end{gathered}[/tex]
Thus, area of the enlarged picture is 81 times the area of the original picture.
Thus, option (E) is the correct solution.
