Answer:
Number of sides-7.
Step-by-step explanation:
There is a formula to find the number of diagonals if the number of sides are known. The formula is d=n(n-3)/2.
Here d = 14, hence 14x2 = 28 = n^2–3n, or
n^2–3n-28=0, or
(n-7)(n+4) = 0.
Hence the number of sides, of the regular polygon is n, = 7.
