To find the width of the park, you can divide the area by the length using scientific notation.
Given:
- Area = \( 1.36 \times 10^8 \) ft²
- Length = \( 1.6 \times 10^4 \) ft
We can set up the division as follows:
\[ \text{Width} = \frac{\text{Area}}{\text{Length}} = \frac{1.36 \times 10^8}{1.6 \times 10^4} \]
To simplify this division, we will divide the coefficients and subtract the exponents of the powers of 10:
-
Divide the coefficients: \[ \frac{1.36}{1.6} = 0.85 \]
-
Subtract the exponents: \[ 10^{8 - 4} = 10^4 \]
Now, combine the results: \[ \text{Width} = 0.85 \times 10^4 \]
To express it in proper scientific notation, we adjust \(0.85\) to \(8.5\) by reducing the exponent on the \(10\): \[ 0.85 \times 10^4 = 8.5 \times 10^{3} \]
Thus, the width of the park is \(8.5 \times 10^3\) ft.
The correct response is: 8.5×10³ ft.
