Answer 2

Step-by-step explanation:

Since the perimeter of a triangle (has side a, b, and c) equals a+b+c, then in an equilateral triangle the sides are equal. Therefore, the perimeter of an equilateral triangle is 3a.

P=3a

One side of the equilateral triangle is 18 inches. Since the equilateral triangle is three equal sides, plug the number 18 into "a".

P=3(18)

Then P=54
