Answer:
Rs. 134.4
Step-by-step explanation:
We know area of a square is s² where s is the side
Now, ar(square field) = 64 m²
Let the sides of field be s
s² = 64
s = 8m
Fencing is done on the perimeter of any region
Thus, Perimeter of field(P) = 4 x s = 4 x 8 = 32m
Cost of fencing = Rate of fencing x Perimeter of field
Cost of fencing = 4.2 * 32 = Rs. 134.4

Answer:
THE COST OF FENCING WOULD BE 75.20
Step-by-step explanation:
FIRST WE HAVE TO FIND THE PERIMETER SO WE HAVE TO FIND SIDE
SIDE = UNDEROOT OF AREA = 4m
so the side is, 4m
now perimeter = 4*4 = 16m
now cost of fencing = 4.20*16 = rupees 75.20
