0.4 acres

Answer 1

To find the area of the planting land needed for 8,000 seeds when the planting density is 20,000 seeds per acre, you can use the formula:

\[
\text{Area (acres)} = \frac{\text{Number of seeds}}{\text{Planting density (seeds per acre)}}
\]

Substituting in the values:

\[
\text{Area} = \frac{8,000 \text{ seeds}}{20,000 \text{ seeds/acre}} = 0.4 \text{ acres}
\]

So, the correct answer is **0.4 acres**.
