The length of a rectangle is 15 inches and the breadth 12 inches. Calculate its area in SI units.

Answer

To calculate the area of a rectangle given its dimensions in inches and convert it to SI units (square meters), follow these steps:

### Step-by-Step Solution:

1. **Identify the dimensions of the rectangle**:
- Length = 15 inches
- Breadth = 12 inches

2. **Convert inches to meters**:
- We know that 1 inch = 0.0254 meters.
- Therefore, to convert the length from inches to meters:
\[ \text{Length in meters} = 15 \, \text{inches} \times 0.0254 \, \text{meters/inch} = 0.381 \, \text{meters} \]
- To convert the breadth from inches to meters:
\[ \text{Breadth in meters} = 12 \, \text{inches} \times 0.0254 \, \text{meters/inch} = 0.3048 \, \text{meters} \]

3. **Calculate the area of the rectangle**:
- The formula for the area of a rectangle is:
\[ \text{Area} = \text{Length} \times \text{Breadth} \]
- Substituting the values we converted:
\[ \text{Area} = 0.381 \, \text{meters} \times 0.3048 \, \text{meters} \]
- Performing the multiplication:
\[ \text{Area} = 0.1161 \, \text{square meters} \]

4. **Final result**:
- The area of the rectangle in SI units is:
\[ \text{Area} = 0.1161 \, \text{m}^2 \]
