Answer 1

Answer:

₹35,700

Step-by-step explanation:

Area of a square=Side^2

Area of this square=11025 m^2

Hence, Side^2= 11025m^2

S^2= 11025m^2

S=Under root 11025

Hence, s=105

Thus,The side measures 105m

Perimeter of a square=4* Side

Perimeter of the square = 4*105

=420m

Rate or cost of fencing=₹85 per metre

Hence, Total cost for fencing= 420*85

=₹35,700

Hence, the total cost to fence the field is ₹35,700
