A heptagon has seven sides, and an octagon has eight sides. 4 heptagons and 5 octagons then have (4*7)+(5*8) = 68 sides altogether
A decagon has ten sides, a heptagon seven, and an octagon eight. So in 4 decagons, 4 heptagons, and 3 octagons there are 4*10 + 4*7 + 3*8 = 40 + 28 + 24 = 92 sides altogether.
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.
An octagon has eight sides, so three octagons altogether have 8 * 3 = 24 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.
A decagon has ten sides and an octagon has eight, so in 3 decagons and 5 octagons there are (3*10)+(5*8) = 30 + 40 = 70 sides altogether.
A decagon has ten sides, a heptagon seven, and an octagon eight. So in 4 decagons, 4 heptagons, and 3 octagons there are 4*10 + 4*7 + 3*8 = 40 + 28 + 24 = 92 sides altogether.
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.
An octagon has eight sides, so three octagons altogether have 8 * 3 = 24 sides.
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.
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.
A decagon has ten sides and an octagon has eight, so in 3 decagons and 5 octagons there are (3*10)+(5*8) = 30 + 40 = 70 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.
heptagons have 7 sides pentagons have 5 sides therefore 4 x 7 = 28 4 x 5 = 20 Total 48 sides.
Polygon means many sides. Octagon mean eight sides. Not all polygons are octagons, but all octagons are polygons. Examples of other polygons are triangles, squares, parallelograms, rhombuses, pentagons, hexagons, heptagons, decagons
A decagon has 10 sides and a heptagon has 7. So five decagons and five heptagons have 5*10 + 5*7 = 50 + 35 = 85 sides.
There are pentagons, hexagons, heptagons, octagons, et cetera.
