The length of a rectangular field is 100 m and its breadth is 40 m. What will be the area of the field?

Options

A. `(4 xx 10^(2)) sq m`
B. `(4 xx 10) sq m`
C. `(4 xx 10^(4))sq m`
D. `(4 xx 10^(3))sq m`

Answer

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

### Step 1: Identify the dimensions of the rectangle
- The length of the rectangular field is given as 100 meters.
- The breadth of the rectangular field is given as 40 meters.

### Step 2: Use the formula for the area of a rectangle
- The formula for the area \( A \) of a rectangle is:
\[ A = \text{length} \times \text{breadth} \]

### Step 3: Substitute the values into the formula
- Substitute the values of length and breadth into the formula:
\[ A = 100 \, \text{m} \times 40 \, \text{m} \]

### Step 4: Calculate the area
- Now, perform the multiplication:
\[ A = 100 \times 40 = 4000 \, \text{m}^2 \]

### Step 5: State the final answer
- The area of the rectangular field is \( 4000 \, \text{m}^2 \).
