What is the required linear feet of plastic snap edge for a 15' by 30' patio?

To determine the required linear feet of plastic snap edge for a patio that measures 15 feet by 30 feet, you first need to calculate the perimeter of the patio. The perimeter can be found by adding together all the sides of the rectangle.

For a rectangular area, the formula for the perimeter (P) is:

P = 2(length + width)

In this case, the length is 30 feet and the width is 15 feet. Plugging these values into the formula gives:

P = 2(30 + 15)

P = 2(45)

P = 90 feet

Therefore, the required linear feet of plastic snap edge to enclose the patio is 90 feet. This amount is necessary to ensure that the edges of the patio are well defined and to prevent erosion or shifting of the materials used within the patio area.
