Question

6) The area of a square field is 1.69 ares. Find the cost of fencing the field at
Rs 3.75 per metre.​

Answer 1

Cost of fencing = ₹67,500

So the length of fence = 67,500/75=900 m.

We know that the perimeter of square field = length of fence = 900 m.

Here,

Perimeter of a square = 4 * Length of its side,

Substituting the values,

Length of the side of a square = Perimeter/4,

So we get,

=900/4

=225 m.
