Question

the breadth of a rectangular Park is 72 metre if 4 kilometre 48 metre long wire is required for fencing itfind the length of the park​

Answer 1

✪SOLUTION✪

★Given :

⋆ Breadth of rectangular park is

  72 metre.

⋆  Size of wire is 3km 48m.

   = 3 × 1000 + 48

   = 3048 m

★To find :

⋆ The length of the park​

it is gien that 3048 m wire

is used to fencing the field

So, 3048m is perimeter.

Let the length required is 'l'

Therefore,

Perimeter of rectangle =

2 ( length + breadth)

⇒ 3048 = 2 (l + b)

⇒ 3048 = 2 (l + 72)

⇒ 3048 ÷ 2 = (l + 72)

⇒ 1524 = (l + 72)

∴ l =1524 - 72 = 1452 m

Answer 2

Answer:

⏺️ Question

the breadth of a rectangular Park is 72 metre if 4 kilometre 48 metre long wire is required for fencing it find the length of the park.

⏺️ To find

The length of fencing wire required

⏺️ Solution

Let the length be x

So, the length of wire =

$3 \times 1000 + 48$

$3048$

Hence the perimeter of park = 3048 cm

We know that

$\huge \bf {P = \: 2 (\: L + B)}$

$3048 = 2 \: (l + b)$

$3048 = 2(x + 72)$

$3048 \div 2 = x + 72$

$1524 = 72x$

$x = 1524 - 72$

$1452$

Hence, length of fence = 1452 cm
