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.
There are pentagons, hexagons, heptagons, octagons, et cetera.
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.
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.
