The length of the wooden strip required to frame a photograph having length and breadth as 39.5 cm and 31 cm respectively, is _____

Options

A. 79cm
B. 1224.5cm
C. 141cm
D. 70.5cm

Answer

To find the length of the wooden strip required to frame a photograph, we need to calculate the perimeter of the rectangular photograph. The formula for the perimeter \( P \) of a rectangle is given by:

\[ P = 2 \times ( \text{Length} + \text{Breadth} ) \]

### Step-by-step Solution:

1. **Identify the Length and Breadth**:
- Length \( L = 39.5 \, \text{cm} \)
- Breadth \( B = 31 \, \text{cm} \)

2. **Substitute the values into the perimeter formula**:
\[ P = 2 \times (39.5 + 31) \]

3. **Calculate the sum of Length and Breadth**:
\[ 39.5 + 31 = 70.5 \, \text{cm} \]

4. **Multiply the sum by 2 to find the perimeter**:
\[ P = 2 \times 70.5 = 141 \, \text{cm} \]

5. **Conclusion**:
The length of the wooden strip required to frame the photograph is **141 cm**.
