Answer:
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)
