Answer:

Ratio of length to bradth = 5:3

So, let length = 5x and breadth = 3x.

Cost of fencing = Rs. 7 per m

Total cost = Rs. 2800

Therefore, perimeter = 400 m

2(5x+3x)=400

8x=200

x=25

So, length = 125 m

Breadth = 75 m

Area = 125×75=9375 m

Answer:

Length = 125m and breadth = 75m

Step-by-step explanation:

Let length be 5x m and breadth be 3x m .

So, the perimter of the piece of land = 2×( 5x + 3x) m

= 2× 8x m

= 16x m

A/Q

16x ×24 = 9600

=> 16x = 9600÷24

=> 16x = 400

=> x = 400÷ 16

=> x = 25

So, Length = 5×25m

= 125m

And breadth = 3× 25m

= 75m
