A pentagon has 5 sides. If you have 4 pentagons, you use: 4x5=20. Therefore, 4 seperate pentagons have 20 sides. This is not true if you have them combined however.

A dodecagon has 12 sides, and a pentagon has 5 sides. So 5 dodecagons have 5*12 = 60 sides, and 4 pentagons have 4 * 5 = 20 sides, for a total of 60 + 20 = 80 sides.

A pentagon has fives sides, and a quadrilateral has four. So 2 pentagons and 1 quadrilateral have 2*5 + 4 = 10 + 4 = 14 sides altogether.

Pentagons do not have four sides, they all have 5 sides
