Question

find the no. of edges of a polygon having 20 faces and 12 vertices​

Answer 1

Answer:

30

Step-by-step explanation:

By Euler's formula,

faces + Vertices = Edges + 2

Let us consider the number of edges as x

20 + 12 = x + 2

32 = x + 2

32 - 2 = x

30 = x

Therefore, Number of Edges in the required figure will be 30.
