To find the width of the rectangular park, we can use the formula:

\[ \text{Width} = \frac{\text{Area}}{\text{Length}} \]

Given:

  • Area = \(1.36 \times 10^8 , \text{ft}^2\)
  • Length = \(1.6 \times 10^x , \text{ft}\)

First, we need to clarify the value of \(x\). If we assume \(x = 1\) from the way you've written the length, then:

Length = \(1.6 \times 10^1 , \text{ft} = 16 , \text{ft}\)

Now we can calculate the width:

\[ \text{Width} = \frac{1.36 \times 10^8}{1.6 \times 10^1} \]

Now divide the coefficients and subtract the exponents:

\[ \text{Width} = \frac{1.36}{1.6} \times 10^{8-1} \] \[ \text{Width} = 0.85 \times 10^{7} \]

Now converting \(0.85 \times 10^7\) to scientific notation gives:

\[ 8.5 \times 10^6 , \text{ft} \]

However, if you intended for the value of \(x\) to be different, then please let me know! Assuming that \(x\) was not \(1\) leads to corresponding changes in value. Assuming \(x = 2\) or others would yield:

\[ \text{Length} = 1.6 \times 10^2 , \text{ft} = 160 , \text{ft} \] In which case calculating becomes:

\[ \text{Width} = \frac{1.36 \times 10^8}{1.6 \times 10^2} \] \[ = 0.85 \times 10^{8-2} \] \[ = 0.85 \times 10^6 = 8.5 \times 10^5 , \text{ft} \]

Thus, if we assume \(x = 2\), the width of the park is:

8.5 × 10^5 ft.

So the correct answer is:

8.5 × 10^5 ft.
