Oh, dude, let me grab my calculator for this super intense math problem. So, a decagon has 10 sides, a heptagon has 7 sides, a nonagon has 9 sides, and an octagon has 8 sides. If we add them all up, we get 10 sides x 4 decagons + 7 sides x 5 heptagons + 9 sides x 5 nonagons + 8 sides x 1 octagon = a grand total of 116 sides. Math is fun, right?
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 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 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.
If the octagon is a regular octagon (all eight sides and all eight angles are equal), then it is a regular polygon. If it is not a regular octagon (i.e. if it is an irregular octagon) then is it an irregular polygon.
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 and an octagon has 8. 5*8 + 5*10 = 90 sides
If the octagon is a regular octagon (all eight sides and all eight angles are equal), then it is a regular polygon. If it is not a regular octagon (i.e. if it is an irregular octagon) then is it an irregular polygon.
There are 74 sides in all.
There's 5 triangles but till 3 sides in each, in Hectagon is 8 sides and the 3 Decagons are still 10 sides on it.
There are a number of polygons that are similar to it but if you mean things that look like decagons than nonagon, undecagon, dodecagon, and octagon.
An octagon has eight sides, so three octagons altogether have 8 * 3 = 24 sides.
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.
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.
