Question

The length and breadth of a rectangular piece of land are in the ratio 5:2. If the total cost of fencing it at Rs. 12.5 per meter is Rs.50000, find its length and breadth.

Answer 1

Answer:

length = 1428.55m

breadth = 571.42m

Step-by-step explanation:

let length and breadth be 5x and 2x.

Then, Perimeter of rectangle = 2(5x+2x) = 2*7x = 14x metres

Now, Cost of fencing at Rs 12.5 per m = 14x × 12.5

⇒ Rs 50000 ÷ 12.5 = 14x

⇒ 4000/14 = x

⇒ 285.71 (approx) = x

∴ length = 285.71*5 = 1428.55m

breadth = 285.71*2 = 571.42m

hope it helps.
