Question

the cost of fencing a square field at rs 125 per metre is rs.8000 find the length of each side of the field​

Answer 1

Cost of fencing a square field per metre = Rs.125
And total cost of fencing = Rs.8000
So, the perimeter of square field = 8000125 = 64 m
Suppose length of each side of square field be a.
So perimeter of square field =  4a = 64 m
⇒a = 644 = 16 m
therefore, length of each side of square field = 16 m
