Select the correct answer.

Paul is gathering data about moss growth in a local forest. He measured an area of 11 square centimeters on one particular tree and will come back in 6 months to measure the growth of the moss. If the area covered by moss multiplies by one and a half times each month, approximately how much area will the moss cover when Paul returns?

A. [tex]$99.1 \, \text{cm}^2$[/tex]
B. [tex]$16.5 \, \text{cm}^2$[/tex]
C. [tex][tex]$14.7 \, \text{cm}^2$[/tex][/tex]
D. [tex]$125.3 \, \text{cm}^2$[/tex]

Answer :

To solve the problem, we start with the following information:

- The initial area of moss is [tex]$11\ \text{cm}^2$[/tex].
- The area multiplies by [tex]$1.5$[/tex] each month.
- Paul measures the area again after [tex]$6$[/tex] months.

After [tex]$6$[/tex] months, the area is multiplied by the factor [tex]$1.5^6$[/tex]. We first compute this multiplier:

[tex]$$
\text{Multiplier} = 1.5^6 \approx 11.390625
$$[/tex]

Now, the area after [tex]$6$[/tex] months is calculated by multiplying the initial area by this factor:

[tex]$$
\text{Future Area} = 11 \times 11.390625 \approx 125.296875\ \text{cm}^2
$$[/tex]

Rounding to one decimal place gives approximately [tex]$125.3\ \text{cm}^2$[/tex].

Thus, the correct answer is:

[tex]$$\boxed{125.3\ \text{cm}^2}$$[/tex]
