Area of a rectangle `= L xx B`
Perimeter of a rectangle = 2(L + B) where L and B are the length and breadth of the rectangle respectively.
The area of a rectangle whose length 20 cm and breadth 15 cm is

Options

A. `105 cm^(2)`
B. `300 cm^(2)`
C. `35 cm^(2)`
D. `30 cm^(2)`

Answer

To find the area of a rectangle given its length and breadth, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Length and Breadth:**
- Given: Length (L) = 20 cm
- Given: Breadth (B) = 15 cm

2. **Use the Area Formula:**
- The formula for the area of a rectangle is:
\[ \text{Area} = L \times B \]

3. **Substitute the Values:**
- Substitute the given values into the formula:
\[ \text{Area} = 20 \, \text{cm} \times 15 \, \text{cm} \]

4. **Perform the Multiplication:**
- Calculate the area:
\[ \text{Area} = 300 \, \text{cm}^2 \]

5. **State the Final Answer:**
- Therefore, the area of the rectangle is:
\[ \text{Area} = 300 \, \text{cm}^2 \]
