To find the width of the rectangular park, you can use the formula for the area of a rectangle, which is:
\[
\text{Area} = \text{Length} \times \text{Width}
\]
You have the area of the park as \(1.36 \times 10^8\) square feet and the length as \(1.6 \times 10^4\) feet. To find the width, you rearrange the formula:
\[
\text{Width} = \frac{\text{Area}}{\text{Length}}
\]
Now, substituting the given values:
\[
\text{Width} = \frac{1.36 \times 10^8}{1.6 \times 10^4}
\]
To perform the division, you can divide the coefficients and subtract the exponents of 10:
1. Divide the coefficients:
\[
\frac{1.36}{1.6} = 0.85
\]
2. Subtract the exponents:
\[
10^{8 - 4} = 10^4
\]
Combining these results gives:
\[
\text{Width} = 0.85 \times 10^4
\]
To express this in standard scientific notation:
\[
0.85 \times 10^4 = 8.5 \times 10^3 \text{ ft}
\]
Therefore, the width of the park is \(8.5 \times 10^3\) feet or 8500 feet.
