Let's visualize this problem (See the picture below). The red line represents the diagonal that is 14 cm, the green sides represent the 25-cm sides, and the yellow line represents the diagonal that we need to find. From this, you can see that the Pythagorean Theorem can be applied to this problem (Since the diagonals are perpendicular)
a^2+b^2=c^2
14^2+b^2=25^2
196+b^2=625
b^2=429
b=20.71 (approximate)

Find what x is first. since it's a regular polygon all the sides are equal. so 3(x-1) = 5x-6. once you find x put it in one of the sides and multiply the length of the side by the amount of sides.
