The correct Answer is:
To find the area of the path surrounding the rectangular lawn, we will follow these steps: ### Step 1: Calculate the dimensions of the outer rectangle (including the path). - The original dimensions of the lawn are 44 m (length) and 32 m (width). - The path is 4 m wide on all sides, so we need to add 4 m to each side of the rectangle. **Calculation:** - Length of the outer rectangle = 44 m + 4 m + 4 m = 52 m - Width of the outer rectangle = 32 m + 4 m + 4 m = 40 m ### Step 2: Calculate the area of the outer rectangle. - The area of a rectangle is given by the formula: Area = Length × Width. **Calculation:** - Area of the outer rectangle = 52 m × 40 m = 2080 m² ### Step 3: Calculate the area of the inner rectangle (the lawn). - The area of the lawn is given by its original dimensions. **Calculation:** - Area of the inner rectangle = 44 m × 32 m = 1408 m² ### Step 4: Calculate the area of the path. - The area of the path is the difference between the area of the outer rectangle and the area of the inner rectangle. **Calculation:** - Area of the path = Area of outer rectangle - Area of inner rectangle - Area of the path = 2080 m² - 1408 m² = 672 m² ### Final Answer: The area of the path is **672 m²**. ---
