A rectangular field is 50m long and 40m wide. The perimeter of the rectangular field is-

Options

A. 200m
B. 180m
C. 160m
D. 140m

Answer

To find the perimeter of a rectangular field, we can follow these steps:

### Step 1: Identify the Length and Width
The length (L) of the rectangular field is given as 50 meters, and the width (B) is given as 40 meters.

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

### Step 3: Calculate the Sum of Length and Width
Now, we will calculate the sum of the length and width:
\[ L + B = 50 \, \text{m} + 40 \, \text{m} = 90 \, \text{m} \]

### Step 4: Multiply by 2
Next, we will multiply the sum by 2 to find the perimeter:
\[ P = 2 \times 90 \, \text{m} = 180 \, \text{m} \]

### Step 5: Conclusion
Thus, the perimeter of the rectangular field is:
\[ \text{Perimeter} = 180 \, \text{meters} \]
