A rectangular park has an area of 1.36 × 10^8 ft^2. The length of the park is 1.6 × 10^4 ft. Divide the area by the length to find the width of the park. (1 point)

Question

8.5 × 10^5 ft.

8.5 × 10 2^ft.

8.5 × 10^3 ft.

8.5 × 10^4 ft

Answer 1

To find the width of the park, we need to divide the area by the length.

Area = 1.36 × 10^8 ft^2
Length = 1.6 × 10^4 ft

Width = Area / Length

Width = 1.36 × 10^8 ft^2 / 1.6 × 10^4 ft

To divide the numbers in scientific notation, subtract the exponents:

Width = 1.36 / 1.6 × 10^(8-4) ft

Width = 0.85 × 10^4 ft

In standard form, this is:

Width = 8.5 × 10^3 ft

Therefore, the width of the park is 8.5 × 10^3 ft.
