a rectangular park has an area of 1.36 x 10^8 ft^2 . the length of the park is 1.6 x 10^4 ft. divide the area by the length to find the width of the park.

1 answer

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

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

Given that the area of the park is \(1.36 \times 10^8 , \text{ft}^2\) and the length is \(1.6 \times 10^4 , \text{ft}\), you can substitute these values into the formula:

\[ \text{Width} = \frac{1.36 \times 10^8}{1.6 \times 10^4} \]

Now, let's perform the division:

  1. Divide the coefficients: \[ \frac{1.36}{1.6} = 0.85 \]

  2. Subtract the exponents (since they are in scientific notation, we subtract the exponent of the length from the exponent of the area): \[ 10^{8 - 4} = 10^4 \]

So, combining these results, we get:

\[ \text{Width} = 0.85 \times 10^4 \]

To express it in proper scientific notation, \(0.85 \times 10^4\) can be converted to \(8.5 \times 10^3\) (by moving the decimal one place to the right and decreasing the exponent by 1).

Thus, the width of the park is:

\[ \text{Width} = 8.5 \times 10^3 , \text{ft} \]

or

\[ \text{Width} = 8500 , \text{ft} \]
