The sides of a pentagon are 6 cm, 8 cm, 5.4 cm, 6.6 cm and 7 cm long, find its perimeter.

Answer

To find the perimeter of the pentagon with sides measuring 6 cm, 8 cm, 5.4 cm, 6.6 cm, and 7 cm, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the lengths of the sides of the pentagon:**
- Side 1: 6 cm
- Side 2: 8 cm
- Side 3: 5.4 cm
- Side 4: 6.6 cm
- Side 5: 7 cm

2. **Write the formula for the perimeter of a polygon:**
- The perimeter (P) of a polygon is calculated by adding the lengths of all its sides.
- Formula: \( P = \text{Side 1} + \text{Side 2} + \text{Side 3} + \text{Side 4} + \text{Side 5} \)

3. **Substitute the lengths of the sides into the formula:**
\[ P = 6 + 8 + 5.4 + 6.6 + 7 \]

4. **Perform the addition step-by-step:**
- First, add the whole numbers:
- \( 6 + 8 = 14 \)
- \( 14 + 7 = 21 \)
- Now, add the decimal numbers:
- \( 5.4 + 6.6 = 12 \)
- Finally, add the results from both parts:
- \( 21 + 12 = 33 \)

5. **Conclusion:**
- The perimeter of the pentagon is \( 33 \, \text{cm} \).

### Final Answer:
The perimeter of the pentagon is **33 cm**.
