Question

The length and breadth of a rectangular piece of land ace in the ratio of 5:3. If the total cost
of fencing it at < 24 per metre is 9600, find its length and breadth.​​

Answer 1

Total cost of fencing the land at Rs 24per metre=9600

Therefore, the perimeter of the land = 9600÷24

=400

Let the length be 5x and breadth be 3x

Therefore, perimeter of the land= 2(l+b)

400=2(5x+3x)

400=16x

Therefore, x=400÷16

X= 25

THEREFORE, Length= 125 and breadth=75
