SUMMARY
The area of a receiving antenna with an angular spread defined by θ = λ/d can be approximated using the given parameters: λ = 5*10^-2 m and d = 3*10^3 m. The calculated angular spread θ results in a spatial spread S of approximately 1 km. The area is derived from the formula A = (S/2)^2 * π, yielding an area of about 0.54 km², indicating a discrepancy in the initial rough approximation of 1 km. This discussion highlights the importance of precise calculations in antenna area determination.
