Answer:
cost of fencing per metre = 48
total cost = 19200 ..
perimeter of that field = total cost/ cost per metre = 19200/48 = 400m
plz mark as brainlist
we know that length and breadth are in the ratio of 5:3
length be 5x and breadth be 3x..
perimeter = 2(l+b) = 2(5x + 3x) = 2(8x) = 16x
16x = 400m
x= 400m/16 = 25m
length = 5x= 5(25m)= 125m
breadth = 3x = 3(25m) = 75m
