ratio of length and breadth of the rectangular piece equals to 5 ratio 2
the total cost of fencing is rupees per metre equals to 12
the cost of fencing rupees 12 per metre is rupees 25000

Length : breadth = 5:2
Therefore, L=5k and B=2k
Rs. 12= for fencing 1 m
Rs. 25000 = 25000/12= for fencing 2083.4 m
Therefore, Perimeter =2083.4m
2(l+b)=2083.4
2(5k+2k)=2083.4
2(7k)=2084.3
7k=2083.4/2
K=1041.7/7
K=148.8

L=5(148.8)=744m (approx.)
B=2(148.8)=297.6m (approx.)
