Answer 1

Answer :

›»› The cost of fencing a rectangular field is ₹34800.

Step-by-step explanation :

Given :

• Long or length of rectangular field = 260 m.
• Wide or breadth of rectangular field = 175 m.
• ₹40 meter.

To Find :

• Cost of fencing a rectangular field = ?

Knowledge required :

First we will find perimeter of rectangular field after that we will the cost of fencing a rectangular field on the basis of conditions given above.

Formula to calculate the perimeter of rectangular field is given by,

→ Perimeter of rectangle = 2(l + b).

Here,

• l is the Length of rectangular field.
• b is the Breadth of rectangular field.

Units,

• The unit of length is meter (m).
• The unit of breadth is meter (m).

Solution :

We know that, if we are given with the length of rectangular field and breadth of rectangular field then we have the required formula, that is,

→ Perimeter of rectangle = 2(l + b).

By using the formula to calculate the perimeter of rectangular field and substituting all the given values in the formula, we get :

→ Perimeter of rectangle = 2(260 + 175)

→ Perimeter of rectangle = {(2 × 260) + (2 × 175)}

→ Perimeter of rectangle = 520 + (2 × 175)

→ Perimeter of rectangle = 520 + 350

→ Perimeter of rectangle = 870.

∴ The perimeter of rectangular field is 870 m.

Now,

→ Cost of fencing a rectangular field = Perimeter of rectangular field × ₹40 meter.

→ Cost = 870 × 40

→ Cost = 34800.

Hence, the cost of fencing a rectangular field is ₹34800.

Answer 2

Answer:

Given :-

• Length of rectangular field = 260 m
• Width of rectangular field = 175 m
• Cost of fencing per metre = ₹40

To Find :-

Total cost

Solution :-

Firstly we will find perimeter of park

As we know that

$\tt \: Perimeter \: of \: rectangle = 2(l + b)$

Here

L is the length

B is the breadth

$\tt \: Perimeter \: of \: rectangle = 2(260 + 175)$

$\tt \: Perimeter \: of \: rectangle = 2(435)$

$\tt \: Perimeter \: of \: rectangle = 870 \: m$

Let's find total cost

$\tt \:Total \: cost \: = cost \: of \: 1 \: m \times perimeter$

$\tt \: Total \: cost \: = 870 \times 40$

$\tt \: Total \: cost \: = 34800 \: rupees$

Therefore :-

Total cost for fencing is ₹ 34800
