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

I HOPE YOU GET IT .
