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 decagon has 10 sides, a heptagon has 7, a nonagon has 9, and an octagon has 8. So 4 decagons, 5 heptagons, 5 nonagons, and 1 octagon have 4*10 + 5*7 + 5*9 = 1*8 sides = 40 + 35 + 45 + 8 = 128 sides

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

An octagon has eight sides, so three octagons altogether have 8 * 3 = 24 sides.

A decagon has ten sides and a triangle has three, so 5 decagons and 4 triangles have (5*10)+(4*3) = 62 sides altogether.

There are ten sides in a decagon and three sides in a triangle. So in 3 decagons and 5 triangles there are 3*10 + 5*3 = 30 + 15 = 45 sides altogether.

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.

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.

4 decagons = 4*10 = 40 sides 1 quadrilateral = 4 sides Total 40+4 = 44 sides.

A nonagon has nine sides and an octagon has eight, so in 1 nonagon and 5 octagons there are 1*9 + 5*8 = 9 + 40 = 49 sides altogether.

An octagon has eight sides, and a pentagon has five. So 5 octagons and 1 pentagon have 5*8 + 1*4 = 40 + 5 = 45 sides altogether.

any shape that is closed and has no round sides, triangles, squares, pentagons, hexagons, heptagons, octagons, nonagons...

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

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

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 pentagons, hexagons, heptagons, octagons, et cetera.

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.

An octagon has 8 sides. A decagon has 10. So 3*8+10 = 34 sides

There are 64 sides in eight octagons.
