A heptagon has seven sides, a hexagon six, a nonagon nine, and an octagon eight. So in 5 heptagons, 2 hexagons, 4 nonagons, and 3 octagons there are (5*7)+(2*6)+(4*9)+(3*8) = 35 + 12 + 36 + 24 = 107 sides altogether.

A nonagon has 9 sides and a triangle has 3. So there are (5*9)+(1*3) = 48 sides in 5 nonagons and 1 triangle.

A heptagon has seven sides, a nonagon has nine, and a quadrilateral has four. So in 2 heptagons, 3 nonagons, and 3 quadrilaterals there are: (2*7)+(3*9)+(3*4) = 14 + 27 + 12 = 53 sides altogether.

A decagon has 10 sides, and a hexagon has 6. So in 4 decagons and 5 hexagons there are (4*10)+(5*6) = 70 sides

a hexagon has 6 sides and a pentagon has 5 sides so 6+5=11. altogether they would be 11 sides.

They have 49 sides.

A heptagon has seven sides and a nonagon has nine, so in 1 heptagon and 2 nonagons there are 7+(2*9) = 25 sides altogether.

A nonagon has nine sides and a pentagon has five sides. So 4 nonagons and 1 pentagon have 4*9 + 1*5 sides = 41 sides

A nonagon has 9 sides and a triangle has 3. So there are (5*9)+(1*3) = 48 sides in 5 nonagons and 1 triangle.

A hexagon has six sides, and an octagon has eight. 3 hexagons and 3 octagons have 3*6 + 3*8 sides = 18 + 24 sides = 42 sides altogether.

3*6 = 18 sides

A heptagon has seven sides, a nonagon has nine, and a quadrilateral has four. So in 2 heptagons, 3 nonagons, and 3 quadrilaterals there are: (2*7)+(3*9)+(3*4) = 14 + 27 + 12 = 53 sides altogether.

A decagon has 10 sides, and a hexagon has 6. So in 4 decagons and 5 hexagons there are (4*10)+(5*6) = 70 sides

A quadrilateral has four sides, and a hexagon has six. So one quadrilateral and three hexagons have 1*4 + 3*6 sides = 4 + 18 sides = 22 sides.

a hexagon has 6 sides and a pentagon has 5 sides so 6+5=11. altogether they would be 11 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.
