To find the percentage of area damaged after 8 hours of burning, we can substitute \( t = 8 \) into the given function \( P(t) = 12e^{0.08t} \).

  1. Calculate \( P(8) \): \[ P(8) = 12e^{0.08 \times 8} \] \[ P(8) = 12e^{0.64} \]

  2. Calculate \( e^{0.64} \) (using a calculator): \[ e^{0.64} \approx 1.857 \]

  3. Now, substitute this back into the equation: \[ P(8) \approx 12 \times 1.857 \approx 22.284 \]

  4. Finally, round to the nearest whole number: \[ P(8) \approx 22 \]

Thus, the percentage of area that will be damaged by the fire after eight hours is approximately 22%.
