A field of 3.9 mi^2 is being subdivided into 1.3×10^3 family gardens. How many square miles will there be in each garden? Write the answer in scientific notation.

Answer 1

To find the area of each garden, we divide the total area by the number of gardens:

(area)/(number of gardens) = (3.9 mi²)/(1.3×10³) = 3 × 10⁻³ mi².

So, there will be 3 × 10⁻³ or 3.0 × 10⁻³ square miles in each garden.
