To calculate the perimeter of an isosceles triangle, the expression 2[i]s[/i] + [i]b[/i] is used, where [i]s[/i] represents the length of the two congruent sides and [i]b[/i] represents the length of the base. What effect, if any, does increasing the length of the congruent sides have on the expression?
