1. **State the problem:** Calculate the perimeter of a parallelogram with side lengths 2.0 m and 0.7 m. 2. **Formula for perimeter of a parallelogram:** $$\text{Perimeter} = 2(\text{length} + \text{width})$$ 3. **Identify the sides:** The parallelogram has two pairs of equal sides: one pair is 2.0 m and the other pair is 0.7 m. 4. **Apply the formula:** $$\text{Perimeter} = 2(2.0 + 0.7)$$ 5. **Simplify inside the parentheses:** $$2.0 + 0.7 = 2.7$$ 6. **Calculate the perimeter:** $$\text{Perimeter} = 2 \times 2.7 = 5.4$$ 7. **Final answer:** The perimeter of the parallelogram is **5.4 m**.
