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.

74 sides

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

37 sides

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

A quadrilateral has four sides and a pentagon has five. So 2 quadrilaterals and 3 pentagons have 2x4 +3x5 sides = 8 + 15 = 23 sides altogether.

A pentagon has fives sides, and a quadrilateral has four. So 2 pentagons and 1 quadrilateral have 2*5 + 4 = 10 + 4 = 14 sides altogether.

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.

A pentagon has five sides, and a quadrilateral has four sides. So five pentagons and three quadrilaterals have 5*5 + 3*4 sides = 25 + 12 sides = 37 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 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.

heptagons have 7 sides

Heptagons have seven 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.

Altogether there are: (5*5)+(3*6)+(1*8) = 51 sides

There are six sides in a hexagon, five in a pentagon, and three in a triangle. So in 2 hexagons, 2 pentagons, and 1 triangle there are 2*6 + 2*5 + 1*3 = 12 + 10 + 3 = 25 sides altogether.

A dodecagon has 12 sides, and a pentagon has 5 sides. So 5 dodecagons have 5*12 = 60 sides, and 4 pentagons have 4 * 5 = 20 sides, for a total of 60 + 20 = 80 sides.

A heptagon has seven sides, a quadrilateral has four, and a triangle has three. So 4 heptagons, 2 quadrilaterals, and 3 triangles have 4*7 + 2*4 + 3*3 sides = 28 + 8 + 9 sides = 45 sides.

Heptagons have 7 sides and 7 angles.

They add up to (1*10)+(4*4)+(3*5) = 41 sides altogether

There are 11 times 5 = 55 sides in 11 pentagons.

1 pentagon = 5 sides. 55 pentagons = 5*55 = 275 sides.

A hexagon has six sides, and a nonagon has nine. Three hexagons and three nonagons then have (3 x 6) + (3 x 9) = 18 + 27 = 45 sides altogether.
