Question

The length and breadth of a rectangular piece of land are in ratio of 5:3.if the total cost of fencing it at 24per metre is 9600,find it's length and bt
breadth ​

Answer 1

Step-by-step explanation:

Total cost = Rs. 9600

Cost per m = Rs. 24

So, perimeter = 9600 ÷ 24 = 400m

Now, let length and breadth be 5x and 3x.

=> 2(5x + 3x) = 400 m

=> 8x = 200m

=> x = 25m

So, length = 5x = 5 × 25 m = 125 m and breadth = 3x = 3 × 25 m = 75 m
