1. The problem states we need to find the cost of fencing a garden with given dimensions and a cost per meter. 2. First, identify the perimeter of the garden. The garden dimensions given are 2000 cm and 30 m. 3. Convert 2000 cm to meters: $$2000 \text{ cm} = \frac{2000}{100} = 20 \text{ m}$$ 4. So the garden dimensions are 20 m by 30 m. 5. Calculate the perimeter of a rectangle: $$P = 2(\text{length} + \text{width}) = 2(30 + 20) = 2(50) = 100 \text{ m}$$ 6. The fence cost is 20 per meter. 7. Calculate total cost: $$\text{Cost} = 100 \text{ m} \times 20 = 2000$$ 8. Therefore, the total cost of fencing the garden is 2000.
