The side of a rectangular plot are in the ratio 5:3
The area of the plot is 960m2 Find the costof fencing (per round) the plot with barbed wire at the rate ₹3.50 per meter​

Answer 1

Answer:

Rs. 448/-

Step-by-step explanation:

The side of rectangular plot is 5:3

The area of the plot is 960m2

Area of rectangle is l*b = 960

According to the question l and b are 5x,3x

Area 5x*3x = 960

15x^2 = 960

x^2= 960/15

x^2 = 64

x= 8

So l = 5*8 = 40

b = 3*8 = 24

To fencing the area, we need to find perimeter of the rectangular plot

Perimeter of rectangle is2(l+b)

2(40+24)

2*64

128m

The cost of fencing to per meter is Rs. 3.50

Then, 128m to fence it 128*3.50 = 448

Rs. 448
