Question

how much would it cost to erect a fence around a 4 hectare square shaped farm if it cost rupee 23permetre?

Answer 1

Hey!

_______________________

Area of the square shaped farm = 4 hectare


1 hectare = 10,000 m^2

Thus , 4 hectare = 40000 m^2

Area of square = side^2
40000 = side^2
Side = √40,000
Side = 200 m

Perimeter of square = 4 × side
Perimeter = 4×200
= 800 m

Cost of fencing 1 m = Rs 23
Cost of fencing 800 m = 800×23
= Rs. 18,400
