A piece of paper of dimensions 1.5 m x 20 cm has area :

Options

A. `30m^2`
B. `300 cm^2`
C. `0.3 m^2`
D. `3000m^3`

Answer

To find the area of a piece of paper with dimensions 1.5 m and 20 cm, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the dimensions**: The dimensions of the paper are given as 1.5 meters and 20 centimeters.

2. **Convert units to a common measurement**: Since the dimensions are in different units (meters and centimeters), we need to convert them to the same unit. We will convert 20 centimeters to meters.
- To convert centimeters to meters, we use the conversion factor: 1 meter = 100 centimeters.
- Therefore, \( 20 \text{ cm} = \frac{20}{100} \text{ m} = 0.2 \text{ m} \).

3. **Use the area formula**: The formula for the area \( A \) of a rectangle is given by:
\[ A = \text{length} \times \text{breadth} \]
Here, the length is 1.5 m and the breadth is 0.2 m.

4. **Calculate the area**:
\[ A = 1.5 \text{ m} \times 0.2 \text{ m} = 0.3 \text{ m}^2 \]

5. **Final result**: The area of the piece of paper is \( 0.3 \text{ m}^2 \).

### Summary:
The area of the piece of paper with dimensions 1.5 m x 20 cm is \( 0.3 \text{ m}^2 \).
