Answer 1

Given :

⬤ Length of Rectangle is 116 m .

⬤ Breadth of Rectangle is 112 m .

To Find :

⬤ Length of Rope needed to Fence it 3 times .

Formula Used :

$\bf[\:{Perimeter \: of \: Rectangle = 2(l+b)}\:]$

• l = Length
• b = Breadth

Solution :

First , We have to Calculate Perimeter of Rectangle . Hence ,

• Length = 116 m .
• Breadth = 112 m .

According to the Formula :-

2 (l + b)

2 (116 + 112)

2 (228)

456

Therefore , The Perimeter of Rectangle is 456 m .

Now :

As given that , We have to Find Length of Rope Needed to Fence it 3 times . Hence ,

456 × 3

1368

Therefore , Length of Rope Needed to Fence it 3 Times is 1368 m .

Option 1) 1368 m is Correct.

Answer 2

$\huge\underline{\bf \orange{AnSweR :}}$

According to the Formula :-

2 (l + b)

• 2 (116 + 112)

• 2 (228)

• 456

Therefore , The Perimeter of Rectangle is 456 m .

Now :

As given that , We have to Find Length of Rope Needed to Fence it 3 times . Hence ,

• 456 × 3= 1368

Therefore , Length of Rope Needed to Fence it 3 Times is 1368 m .

Option 1) 1368 m is Correct.
