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

Answer :

To solve this problem, we need to determine how much area will be covered by moss after 6 months, given it multiplies by one and a half times each month.

1. Initial Area: The initial area covered by the moss is 11 square centimeters.

2. Growth Factor: Each month, the area of moss grows by one and a half times, which means a growth factor of 1.5.

3. Time Period: The growth happens over a period of 6 months.

4. Calculating the Final Area:
- For each month, the area covered by moss is multiplied by the monthly growth factor.
- To find the area after 6 months, you multiply the initial area by the growth factor raised to the power of the number of months.

[tex]\[
\text{Final Area} = \text{Initial Area} \times (\text{Growth Factor})^{\text{Number of Months}}
\][/tex]

[tex]\[
\text{Final Area} = 11 \times (1.5)^6
\][/tex]

5. Result: After calculating, the final area covered by moss is approximately 125.3 square centimeters.

Therefore, the correct answer is:

B. [tex]\(125.3 \, \text{cm}^2\)[/tex]
