Answer:

It is given that,

Perimeter of rectangular field = 440 m.

Consider 7x as the length and 4x as the breadth of rectangular field.

So we get,

2(l+b) = Perimeter.

Substituting the values,

2(7x+4x)=440

By further calculation,

2(11x)=440

22x=440

So we get,

x=440/22=11 m.

Here,

Length = 7x=7∗11=77 m.

Breadth = 4x=4∗11=44 m.

We know that,

Cost of fencing = ₹150 per m.

So the cost of fencing 440 m = 150∗440 = ₹ 66,000
