Question

The length and breadth of a rectangular piece of land are in the rate of 5:3. If the total cost of fencing it at the rate of 48 per metre is 19,200, find its length and breadth.

Answer 1

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
