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.
20 :)
Pentagons do not have four sides, they all have 5 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.
heptagons have 7 sides pentagons have 5 sides therefore 4 x 7 = 28 4 x 5 = 20 Total 48 sides.

37 sides
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.

The real answer is 29 . First, find the number of sides for each group of shapes. 1 nonagon: 1 × 9 = 9 4 pentagons: 4 × 5 = 20 Now add to find the total number of sides: 9 + 20 = 29 They have 29 sides in all.
Pentagons do not have four sides, they all have 5 sides
Each decagon has 10 sides, each nonagon has 9 sides and each pentagon has 5 sides. 4 decagons make 40 sides, 2 nonagons make 18 sides and 2 pentagons make 10 sides. When you add them all up together, you get 68 sides in total.
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.
There are (5*6)+(4*5) = 50 sides

A hexagon has 6 sides. To figure out the total number of sides of four hexagons, simply multiply 6 by 4:Total number of sides = 6(4) = 24
