Aydan wants to put a border of LED rope lights around the ceiling of his room. The ceiling is in the shape of a square. The length of one side of the ceiling is 11.4 feet. How many feet of LED rope lights will Aydan need to buy?
We’re calculating perimeter, so we add up the length of all 4 sides, or multiply (l + w) x 2. Since the room is square, we only need the one measurement.
