Formula
Perimeter of equilateral triangle:
P = 3a, where P is Perimeter and a is length of a side
Therefore
(33X + 21) = 3a
a = (33X + 21)/3
Exact value of a can't be determined because we don't know the value of X.
An equilateral triangle has a perimeter of (33x + 21). What is the length of each side of the triangle?
