A dodecagon has 12 sides, and a quadrilateral has 4. So in 2 dodecagons and 4 quadrilaterals there are 2*12 + 4*4 = 24 + 16 = 40 sides altogether.

A pentagon has five sides, and a decagon has ten sides. So 3 pentagons and 5 decagons have (35)+(510) = 65 sides altogether

3*12 + 1*7 = 36+7 = 43 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.

A heptagon has seven sides and a pentagon has five. So 2 heptagons and 2 pentagons have 2*7 + 2*5 = 14 + 10 = 24 sides altogether.

A decagon has 10 sides, a dodecagon 12, and a pentagon 5. So 4 decagons, 5 dodecagons, and 3 pentagons have 4*10 + 5*12 + 3*5 sides = 40 + 60 + 15 = 115 sides altogether.

There are 12 sides in a dodecagon, 5 in a pentagon, and 10 in a decagon. So in 4 dodecagons, 3 pentagons, and 2 decagons there are 4*12 + 3*5 + 2*10 = 48 + 15 + 20 = 83 sides altogether.

There are 12 sides in a dodecagon, 4 in a quadrilateral, and 3 in a triangle. So in 4 dodecagons, 4 quadrilaterals, and 4 triangles there are 4*12 + 4*4 + 4*3 = 48 + 16 + 12 = 76 sides altogether.

They have 12 sides

heptagons have 7 sides pentagons have 5 sides therefore 4 x 7 = 28 4 x 5 = 20 Total 48 sides.
