Question

The length of a rectangular field is 280 m. If the ratio between the length and breadth of the field is 5 : 3 , then the breadth of the field will be​

Answer 1

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.

Answer 2

Answer:

Hey i dont understand the question but if the perimeter of the rectangular field is 280 m then the answer-

Step-by-step explanation:

Given,

The perimeter of the rectangular field = 280

Length=?

Breadth=?

Let the length be 5x and the breadth be 3x

We know that,

Perimeter of rectangle= l×b

A/Q,

5x × 3x = 280 (meters)

15x= 280 (m)

x=280÷ 15(m)

x=18.6 (m)

Therefore,

Length= 3x

= 3× 18.6m

=55.8 m

Breadth=5x

= 5×18.6

= 93 m

If it's incorrect then please forgive me .

Hope it will help you!
