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 return in 5 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]$125.3 \, cm^2$[/tex]
B. [tex]$14.7 \, cm^2$[/tex]
C. [tex]$99.1 \, cm^2$[/tex]
D. [tex]$165 \, cm^2$[/tex]

Answer :

To solve this problem, we need to determine the area that moss will cover after 5 months, given its growth rate.

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

2. Growth Rate: The moss grows at a rate of one and a half times its area each month. This means that every month the area becomes 1.5 times larger than the previous month.

3. Time Frame: We are considering a period of 5 months.

4. Exponential Growth Calculation: To find the area covered by the moss after 5 months, we use the exponential growth formula:
[tex]\[
\text{Final Area} = \text{Initial Area} \times (\text{Growth Rate}^{\text{Number of Months}})
\][/tex]

5. Calculation:
- Substitute the values into the formula:
[tex]\[
\text{Final Area} = 11 \times (1.5^5)
\][/tex]
- The calculation yields approximately 83.53 square centimeters.

Thus, after 5 months, the moss will cover approximately 83.53 cm².

None of the options provided in the question exactly match this calculation. Please double-check the options to ensure they are correct or consider the calculation as accurate given the growth conditions.
