WebJan 24, 2024 · The diagonal formula is a formula for calculating the number of diagonals in various polygons and their lengths. An n-sided polygon’s number of diagonal lines = n (n-3)/2, where n is the number of sides. WebWe can find the number of diagonals of the given polygon with the formula, Number of diagonals = n(n-3)/2. Substituting the value of n = 15. n(n-3)/2 = 15(15-3)/2 = (15 × 12)/2 = 90. Therefore, the polygon has 90 diagonals. Ques 2. Determine the diagonal of a rhombus whose area is 50cm2 and one of its diagonal measures is 7cm.
