To find the width of the park, you'll divide the area by the length.
Given:
- Area = \( 1.36 \times 10^8 \) ft²
- Length = \( 1.6 \times 10^4 \) ft
**Calculation:**
\[
\text{Width} = \frac{\text{Area}}{\text{Length}} = \frac{1.36 \times 10^8 \, \text{ft}^2}{1.6 \times 10^4 \, \text{ft}}
\]
To perform the division:
1. Divide the coefficients:
\[
\frac{1.36}{1.6} = 0.85
\]
2. Subtract the exponents:
\[
10^{8 - 4} = 10^4
\]
Now, multiplying these together:
\[
\text{Width} = 0.85 \times 10^4
\]
To express \( 0.85 \) in scientific notation:
\[
0.85 = 8.5 \times 10^{-1}
\]
Thus,
\[
\text{Width} = 8.5 \times 10^{-1} \times 10^4 = 8.5 \times 10^{3} \, \text{ft}
\]
The width of the park is:
\[
\text{Width} = 8.5 \times 10^3 \, \text{ft}
\]
The correct answer is:
**8.5 × 10³ ft.**

The correct answer is:
