the area of square field is 9 hectares.find the cost of fencing it at the rate of rs.32 per metre​

Answer 1

Area of square = side × side

Answer 2

Answer:

We know that

1 hectare=10000 sq.m

therefore

9 hectares=90000 sq.m

We know that

area of square=side×side

90000 = s^2

√90000=s

s=300m

We know that

perimeter of square= 4 × side

P (square) =4×300

=1200m

Given

To fence

1 m = Rs 32

Then,

To fence 1200m= Rs 32×1200 = Rs 38400
