SOLUTION

The given area of the forest is 2000 square kilometers

The rate of decrease is given as 4.75%

The given time is 7 years

The formula for decay is

y=a(1-r)^t

Substituting values gives

y=2000(1-0.0475)^7

Solve for y

\begin{gathered} y=2000(0.7113) \\ y=1423 \end{gathered}

Therefore the new area of the forest is 1423 square meters.

Blababa [14]

Answer:

6*(61^2) and 61^3

Step-by-step explanation:

If the squares have a side length of 61 (assuming this is a cube) our surface area is 6*(61^2) because each side is a square and there are six sides.

As for the volume, we have 61^3.
