Answer:
p = 2 * w + 54
Step-by-step explanation:
To know the number of feet Alice needs, you must calculate the perimeter, the perimeter of a rectangle would be the sum of its sides, that is, twice the width and twice the length.
This time they give us the length that is equal to 27 feet, therefore, the equation of the perimeter would be:
p = 2 * w + 2 * l
p = 2 * w + 2 * 27
p = 2 * w + 54
Therefore, to know exactly what Alice needs, you need to know the value of the width and shortest side.
