Answer:Half of this area is 4802 square meters
Explanation:
The area used for agricultural purposes is equal to half of the total area of the square plot of land.
To find the area used for agricultural purposes, we need to first calculate the total area of the square plot of land.
We can do this by squaring the length of one of the sides of the square and multiplying it by 4.
If the total length of the basement of the fence is 392 meters, then each side of the square plot of land is 392/4 = 98 meters.
The total area of the square plot of land is therefore 98^2 = 9604 square meters. Half of this area is 4802 square meters, which is the area used for agricultural purposes.
