Consider that the initial length and width of the rectangle are given as,

$\begin{gathered} l=20 \\ b=20 \end{gathered}$

After the length is increased by 10%, the new length (L) of the rectangle is calculated as,

$\begin{gathered} L=(1+\frac{10}{100})\cdot l \\ L=(\frac{110}{100})\cdot20 \\ L=22 \end{gathered}$

After the width is decreased by 10%, the new width (B) of the rectangle is calculated as,

$\begin{gathered} B=(1-\frac{10}{100})\cdot b \\ B=(\frac{90}{100})\cdot20 \\ B=18 \end{gathered}$

Then the area (A) of the new rectangle is calculated as,

$\begin{gathered} A=L\times B \\ A=22\times18 \\ A=396 \end{gathered}$

Thus, the new area of the rectangle is 396 square meters.

Use A = P (1 + r/n) ^(nt). Assuming that we're dealing with years here, n = 1, so we have

A = P (1 + r) ^(t), where r is the interest rate as a decimal fraction.

The investment decreases in value, so the common ratio r is (1.000-0.012), or 0.988.

Thus, A = $100,000* (0.988) ^25 = $73947.52 is the current value, after 25 years.
