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
