A:

Answer:The correct answer is option D. [3x² + 7x + 21]/3x²Step-by-step explanation:Perimeter of a triangle = sum of all sidesTo find the perimeter of triangleHere sides are,7/x² , 1/3x and (x + 2)/xPerimeter = 7/x² + 1/3x + (x + 2)/xHere LCM = 3x²Perimeter = (7 * 3)/3x² + (1 * x)/3x² + (x + 2)3x/3x² = [21 + x + 3x² +6x]/3x² = [3x² + 7x + 21]/3x²The correct answer is option D. [3x² + 7x + 21]/3x²
