Question

the width of the room.
& The length and breadth of a rectangular piece of land are 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

Answer:

length= 125

breadth= 75

Step-by-step explanation:

ratio = 5 : 3

let the length and breadth be 5x and 3x

cost of fencing per metre = 24

cost of fencing y metre = 9600÷24

y = 400 m

where y is the perimeter of the rectangular land.

y = 400

2(l + b) = 400

2(l+b)=400

2(5x + 3x) = 400

2(5x+3x)=400

2(8x)=400

8x=200

x=25

so, length= 5x = 5(25) = 125m

breadth = 3x = 3(25)= 75

Answer 2

Answer:

Length = 125m and Breadth = 75m

Step-by-step explanation:

So, It's given that the Cost of fencing is 9600 @ rs24 per m.

Perimeter = Total cost of fencing/ Rate per m

= 9600/24 = 400

Now, as we get the perimeter Now we should let the length and breadth of the rectangular piece of land be 5x and 3x respectively.Then,

2(5x + 3x) = 400 [perimeter of a rectangle = 2(length + breadth) ]

=> 2 x 8x = 400

=> 16x = 400

=> x = 25

Hence length = 5x = 5 x 25 = 125

and breadth = 3x = 3 x 25 = 75

Now if you put the values then 2(l+b) = 2(125 + 75)

= 2 x 200 = 400 = Perimeter
