Answer:

3a

Step by Step Explanation:
  1. The perimeter of a shape (polygon) is equal to the sum of length of all its sides.
  2. A triangle has 3 sides and in the case of an equilateral triangle, all sides are of equal length.
  3. Therefore, the perimeter is equal to three times the length of a side.
    = 3 × a
    = 3a
