Given that
The perimeter of square = 8 km

4*side = 8 km

side = 8/4 km

side = 2 km

Area of the Square = side*side

Area of the Square = 2 km * 2 km

Area of the Square = 4 km²

We know that 1 km = 100 Hectare

then

Area of the Square = 4*100*100 km²

Area of the Square = 4*10⁴ km²

Given perimeter of square field is 8 km

let 'a' be its side

then perimeter = 4a = 8km

[a = 2km]

we know 1 hectares =0.01(km)²

area of filed = a²

= 4km²

then area of hectare = 400/0.01 = 40000 hectares.
