That would violate the triangle inequality. The sum of the measures of any two sides of a triangle must be strictly greater than the measure of the third side. If the perimeter is 12 and one side is 7, that only leaves 5 for the sum of the remaining sides and since 5 is not strictly greater than 7, 7 is not a possible measure of any side of a triangle with a perimeter of 12.
