Answer:

Step-by-step explanation:

15). Perimeter of both the polygons are same.

   Sum of the sides of the triangle = Sum of the sides of the rectangle

   Therefore, the equation will be,

   (x + 6) + (x + 9) + (x + 3) = 2(x + 1) + 2(x + 4)

16). Sum of the measures of all sides of the hexagon = sum of all sides of the triangle

   Therefore, the equation will be,

   6(5x) = (x + 14) + (x + 17) + (8x + 9)
