shown in the figure. In the figure, AED=ADB =BCD= 90°. To seal the envelope she has to
Apply glue along AD and DB. Given that AE=ED=8cm and DC= BC = 14 cm, find the total length
of the sides along which the glue has to be applied
to seal the envelope.

Answer 2

Step-by-step explanation:

$\begin{gathered}\implies \sf C.l= Amount - Principal \\ \\ \implies\sf C.l = 11390.625 - 9000 \\ \\ \implies \underline { \boxed {\sf C.l = 2390.625}}\end{gathered}$

$\begin{gathered}\implies\underline{ \boxed{ \sf Amount=P \bigg(1 + \frac{r}{100} { \bigg)}^{n}}} \\ \\\implies \sf Amount=9000 \bigg(1 + \frac{12.5}{100} { \bigg)}^{2} \\ \\\implies \sf Amount = 9000 \bigg( 1 + \frac{1}{8} { \bigg)}^{n} \\ \\ \implies\sf Amount = 9000 \bigg( \frac{8 + 1}{8} { \bigg)}^{2} \\ \\ \implies \sf Amount = 9000 \bigg( \frac{9}{8} { \bigg)}^{2} \\ \\\implies \sf Amount = 9000 \times \frac{81}{64} \\ \\ \implies \sf Amount =11,390.625\end{gathered}$

$\begin{gathered}\implies \sf C.I= Amount - Principal \\ \\ \implies \sf C.I = 11390.625 - 9000 \\ \\ \implies \underline { \boxed {\sf C.I = 2390.625}}\end{gathered}$
