Final answer:
To calculate the perimeter of a rectangle 10 feet long and 4 feet wide, substitute the values into the formula Perimeter = 2L + 2W to get a total perimeter of 28 feet.
Step-by-step explanation:
To calculate the perimeter of a rectangle with the length (L) of 10 feet and width (W) of 4 feet using the formula Perimeter = 2L + 2W, we follow these steps:
- Substitute the given values into the formula: Perimeter = 2(10) + 2(4).
- Multiply the length and the width by 2: Perimeter = 20 + 8.
- Add the results to find the total perimeter: Perimeter = 28 feet.
Therefore, the perimeter of the rectangle is 28 feet.
