Somesh wants to fence a rectangular field of length 150 m and breadth 80 m with four rounds of rope. What is the total length of rope he must use?

Options

A. 460 m
B. 1840 m
C. 920 m
D. 380 m

Answer

To find the total length of rope Somesh must use to fence a rectangular field with four rounds of rope, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the dimensions of the rectangular field**:
- Length (L) = 150 m
- Breadth (B) = 80 m

2. **Calculate the perimeter of the rectangle**:
- The formula for the perimeter (P) of a rectangle is given by:
\[ P = 2 \times (L + B) \]
- Substitute the values of L and B:
\[ P = 2 \times (150 + 80) = 2 \times 230 = 460 \text{ m} \]

3. **Determine the total length of rope for four rounds**:
- Since Somesh wants to use four rounds of rope, we multiply the perimeter by 4:
\[ \text{Total Length of Rope} = 4 \times P = 4 \times 460 = 1840 \text{ m} \]

4. **Final answer**:
- The total length of rope Somesh must use is **1840 meters**.
