Question

f the lengthand the breadth of a garden are 45 ½ m and 23 ½ m , respectively , find the length of barbed wire required to build a three layer fence around it.

Answer 1

Given :

• Length of the garden = 45(1/2) m.
• Breadth of the garden = 23(1/2) m.

To find :

• The length of barbed wire required to build a three layer fence around it =?

Formula Used :

• Perimeter of the rectangle = 2(length + breadth)

Step-by-step explanation :

It is Given that,

Length of the garden = 45(1/2) m.

Breadth of the garden = 23(1/2) m.

As We know that,

Perimeter of the rectangle = 2(length + breadth)

Substituting the values in the above formula, we get,

= 2[45(1/2) + 23(1/2)]

= 2[91/2 + 47/2]

= 2[138/2]

= 138.

Therefore, We got the perimeter of the garden = 138 m.

Now,

The length of barbed wire required to build a three layer fence around it,

= 3 × 138

= 414.

Hence, 414 m is the length of barbed wire required to build a three layer fence around it.

➦Given : -

• Length = 45(1/2) m.
• Breadth = 23(1/2) m.

➦To Find : -

• The length of barbed wire required to build a three layer fence around it...

➦Formula Used : -

$\leadsto\sf{{ \small{ \bold{ \bold{ \bold{ \green{Perimeter\:of\:Rectangle=2(l+b)}}}}}}}$

➦On Substituting Values : -

⇒2 [45(1/2) + 23(1/2)]

⇒2 [9(1/2) + 47/2]

⇒2 [138/2]

⇒138 [Answer]

➙Therefore , the perimeter of rectangle is 138m ..

➦Now ,

• It is given that the length of barbed wire required to build a three layer fence around it.

➦So ,

⇒3 × 138

⇒414 [Answer]

➙Hence , the length of the barbed wire is 414m ..
