A RECTANGULAR PARK IS 56 M WIDE AND 98 M LONG FIND THE LENGTH OF WIRE NEEDED TO PUT FENCE AROUND IT ?

Answer 1

$\dagger \underline{\large \: \: {\frak{correct \: question : }}}$

A rectangular park is 56m wide and 98m long . Find the length of wire needed to put fence around it ?

$\dagger \underline{\large \: \: {\frak \red {detailed \: \: explanation \: of \: the \: solution : }}}$

In this question it is asked that there is a rectangular park which is 56m wide and 98m long . And we have to find the length of wire which will be needed to put a fence around it.

Now by putting the revlant formula with revlant values we can find the required Formula .

Now ,

Let the length of the wire be x.

Now , here we need to find up the length means the perimeter required.

Therefore,

$\dagger\underline{\large \: \: {\frak{perimeter \: of \: a \: rectangle \: = 2(l + b)}}}$

$\dagger\underline{\large \: \: {\frak{x = 2(56 + 98)}}}$

$\dagger\underline{\large \: \: {\frak{x = 2(154)}}}$

$\dagger \underline{\large \: \: {\frak{x = 2 \times 154}}}$

$\dagger \underline{\large{\frak{x = 308m}}}$

• Hence,The length of wire of 308m will be required to put a fence around it.

• A rectangle is a polygon which has 4 sides.
• Area of rectangle = length × breadth
• Area of square = side × side = side²
• Area of right angled triangle = 1/2 × products of sides making right angle.
• Area of triangle =1/2× base × height
• Area of parallelogram = base × height
• Area of rhombus= 1/2 × product of length of diagonals.
• Area of trapezium = 1/2× sum of lengths of parallel sides × height .
• Diameter = 2×r
• Area of circle = πr².

Answer 2

★ Concept:-

Here in this question, concept of perimeter of rectangle is used. We have given length and breadth of rectangle to be 98 metre and 56 metre respectively and we are asked to find the length of fence to be put around that park. As we know that fencing is always done at the boundary of the field or park and fencing can be find by adding the sides of park. There is a short method to shorten the calculation is to apply formula for perimeter of rectangle.

So let's do it!!

___________________________________

★ Formula used:-

Perimeter of rectangle=2(L+B)

Here:

   • L=Length

   • B=Breadth

___________________________________

★ Solution:-

Let's apply formula for finding perimeter of park!

Perimeter of rectangular park=2(L+B)

Perimeter of rectangular park=2(98m+56m)

Perimeter of rectangular park=2(154m)

Perimeter of rectangular park=308metre

Since the value of perimeter of the park is 308metre, it will require fence of 308 metre.

So the required length of fence is 308 metre.

★ Points to remember:-

  • Always remember that fencing is always done at the boundary

     of a given field or park and if you want to find the length of

     fencee you have to find its perimeter.

  • Ploughing is always done in full field so inorder to find the rate

     off ploughing you must find the area.
