Application of fuzzy logic and fuzzy mathematics are increasing widely all around the world. This paper mainly intends to propose a new approach to compute distance between fuzzy number. This new distance, is a meter on the set of all fuzzy numbers with continuous left and right spread functions. Using this metric we approximate parametric fuzzy number with polynomial parametric fuzzy numbers.
