How many feet of rope are needed to tie off a hazardous waste area that is 34 feet long and 20 feet wide?

To determine how many feet of rope are required to tie off a hazardous waste area that measures 34 feet long and 20 feet wide, you first need to calculate the perimeter of the rectangular area.

The perimeter of a rectangle is calculated using the formula:
Perimeter = 2 * (Length + Width).

In this case, you would substitute the length and width into the formula: Perimeter = 2 * (34 feet + 20 feet) = 2 * 54 feet = 108 feet.

Thus, you need 108 feet of rope to completely tie off the area, making this the correct choice. Calculating the perimeter ensures that you encircle the entire area safely, which is essential for proper hazard management in sanitation work.
