Answer 1

${\huge{\fcolorbox{Black}{red}{Answer}}}$

Area of square field = 64 hectare

1 hectare = 10000 sq.m.

So, 64 hectare = 640000 sq.m.

So, Area of square field = 640000 sq.m.

Area of Square = side × side

Side² = 640000 sq.m.

side = √640000

Side = 800

Perimeter of Square = 4 × side

Perimeter of Square field = 4 × 800 = 3200 m

Cost of fencing 1 m = ₹ 21.50

Cost of fencing 3200 m = 21.50 × 3600 = ₹ 68,800

Hence The cost of fencing the square field is ₹ 68,800

Answer 2

Answer:

Question :-

The area of square field is 64 hectare find the cost of fencing at rupees is 21.50 per m.

Answer :-

Area of the field = 64 hectares

= (64×10000)m² = 640000m².

∴ Side of the field = √Area = √640000 m = 800m

∴Perimeter of the field = (4×800)m= 3200 m.

∴Length of wire required for fencing = 3200m.

Cost of fencing = ₹(3200×21.50) = ₹68800.
