Question

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.

Answer 1

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

Area of the park: 1.36 x 10^8 ft^2
Length of the park: 1.6 x 10^4 ft

Width of the park = Area / Length
= (1.36 x 10^8 ft^2) / (1.6 x 10^4 ft)

When dividing, we subtract the exponents:

1.36 x 10^8 / 1.6 x 10^4 = (1.36 / 1.6) x (10^8 / 10^4) = 0.85 x 10^(8-4) = 0.85 x 10^4

Therefore, the width of the park is 0.85 x 10^4 ft.
