Question

A farmers has a rectangular field of length and breadth 140m and 110m respectively . He wants to fence it 5 rounds of rope. What is the total length of rope he must use?​

Answer 1

Answer :

• The farmer must use 2500metres of rope.

Explanation :

Question says that,

Find the length of fencing rope 5 times a rectangular field of length 140 and width 110m.

Here, the fencing is the perimeter of the field.

Perimeter of the rectangle is given by : 2(l + b)

Where,

• l is length 140m.
• b is the width 110m.

We know that, the required lemgth of the rope :

→ 5 × the perimeter of the field.

So,

→ 5 × 2(140 + 110)

→ 5 × 2(250)

→ 5 × 500

→ 2500m.

Required length of the rope is 2500m.

$\huge\red{\mid{\underline{\overline{\textbf{Solution\:࿐}}}\mid}}$

Given:

Length =140m.

width =110m.

To find Perimeter of rectangle :

$2(l + b)$

the required length of the rope :

➪5 × the perimeter of the field.

So,

➪ 5 × 2(140 + 110)

➪ 5 × 2(250)

➪ 5 × 500

➪ 2500m.
