Let the length and width be 5a and 3a respectively
Cost of fencing = Rs 9600
Rate of fencing = Rs 24/m
Perimeter = Cost / Rate
=> 2 (L +B) = 9600/24
=> 2(5a+3a) = 400
=> 8a = 200
=> a = 25
Length of field = 125 m
Width of field = 75 m
Cost of fencing = Rs 9600
Rate of fencing = Rs 24/m
Perimeter = Cost / Rate
=> 2 (L +B) = 9600/24
=> 2(5a+3a) = 400
=> 8a = 200
=> a = 25
Length of field = 125 m
Width of field = 75 m
