Good evening ,Answer:D.60Step-by-step explanation:Perimeter of the the square = 4(3x+3) = 12x + 12perimeter of the pentagon = 5(x+8) = 5x + 40the perimeters are equal means 12x + 12 = 5x + 4012x + 12 = 5x + 40 ⇔ 7x = 28 ⇔ x = 4x=4 ⇒ 4(3x+3) = 4×15 = 60       ⇒5(x+8) = 5(4+8) = 60 :)

The answer is d step by step
