Question

find the numbers of diagonals of a polygon with 11side​

Answer 1

Step-by-step explanation:

The formula for calculating the number of diagonals is:

diag = n*(n - 3)/2

where "diag" is the number of diagonals, and n is the number of vertices (remember, the number of vertices of a polygon is the same as the number of sides).

For example, find the number of diagonals in a polygon with 22 sides. We know that this polygon has 22 vertices. Simply plug this into the formula.

diag = 22*(22 - 3)/2

diag = 22*(19)/2

diag = 209

So, a polygon with 22 sides has 209 diagonals.

Answer 2

Answer:

as we know

diagonal=n(n-3)÷2

here n= no. of side

now coming to the equation

n(n-3)÷2

= 11(11-3)÷2

= (11×8)÷2

= 88÷2

= 44 (answer)
