From the question,

The cost of fence = ₹ 24 per mater

The total cost of fencing a rectangular piece of land = ₹ 9600

Let the length of the rectangular field = 5x

The breadth of the rectangular field = 3x

Then,

perimeter of the rectangular land = 2 ( l + b )

= 2 (5x + 3x)

= 2 (8x)

= 16x

Perimeter of the given field = (total cost of fencing / Rate of fencing)

16x = (9600/24)m

16x = 400m

x = 400/16

x = 25

∴ the length of the rectangular field = 5x = 5 × 25 = 125m

The breadth of the rectangular field = 3x = 3 × 25 = 75m
