Question

The length and the breadth of rectangular piece of land are in ratio 5:2 if the total cost of fencing it at rupees 12.5 per metre is rupees 25000 find length and breadth

Answer 1

Rate of fencing = 12.5/m^2
Cost of fencing =25000
Perimeter of field = cost / rate
=25000/12.5
=2000m
Let the length = 5x
Breadth = 2x
Perimeter of field =2[l+b]
2000 = 2[5x+2x]
2000/2 =7x
x = 1000/7
x=142.86
Length = 5×142.86 = 714.3m
Breadth = 2×142.86 = 285.72m
