The length and the breadth of a rectangular field are 240 m and 180 m respectively. It is fenced with three rounds of a rope. Find the length of the rope.

Answer

To find the length of the rope used to fence the rectangular field, we need to follow these steps:

### Step 1: Identify the dimensions of the rectangular field
- The length (L) of the rectangular field is given as 240 m.
- The breadth (B) of the rectangular field is given as 180 m.

### Step 2: Calculate the perimeter of the rectangular field
The formula for the perimeter (P) of a rectangle is:
\[ P = 2 \times (L + B) \]

Substituting the values:
\[ P = 2 \times (240 + 180) \]

### Step 3: Simplify the expression inside the parentheses
First, calculate the sum of the length and breadth:
\[ 240 + 180 = 420 \]

### Step 4: Multiply by 2 to find the perimeter
Now, substitute back into the perimeter formula:
\[ P = 2 \times 420 = 840 \, \text{m} \]

### Step 5: Calculate the total length of the rope
Since the rope is used to fence the field three times, we multiply the perimeter by 3:
\[ \text{Length of rope} = 3 \times P = 3 \times 840 \]

### Step 6: Perform the multiplication
Now, calculate the total length of the rope:
\[ 3 \times 840 = 2520 \, \text{m} \]

### Final Answer
The length of the rope used to fence the rectangular field is **2520 meters**.
