Question 987461
This question does not make sense.  You have three expressions, one for each side of the triangle.  A triangle has two dimensions because it is a two-dimensional figure.  You have no other information to show relation among the sides and no area nor perimeter information.  The sides themselves are not dimensions.  They are just a list of expressions to represent the lengths of each side making the triangle.
