Answer:
let the length and breadth be = 5x and 3x respectively
perimeter of rectangle = 2( l+b)
= 2(5x+3x)
= 16x
cost of fencing = 24 per metre
total cost = 24 × 16x
9600 = 384x
x = 25
therefore
length = 125
breadth = 75

Step-by-step explanation:
Total Cost=₹9600
Per metre fencing=9600÷24
=400m
Perimeter of rectangle=2(l+b)
400m=2(5x+3x)
400=2×8x
400=16x
400÷16=x
25m=x
l=5×25=125m
b=3×25=75m
