Answer 2

Given
Let the ratio be 3x and 2x
Length =3x
Breadth = 2x

Cost of fencing the field at per meter = ₹6.50

Total cost of fencing the field = ₹520

Solution
Perimeter of rectangle =2*(l+b)
=2*(3x+2x)
=2*5x
=10x m
Cost of fencing the field of 10x m = 520 = 10x * 6.50
= 520 = 65x
= x = 520/65
= x = 8

Length is 3x
= 3*8 = 24 m

Breadth is 2x
= 2*8 = 16 m
