The regular octagon will consist of 8 congruent isosceles triangles each having equal angles of 67.5 degrees and an apex angle of 45 degrees.
Equal sides are: square root of 309.019336*2/sin(45)*8 = 10.45250372 cm
Base length: 10.45250372*sin(45)/sin(67.5) = 8 cm
Perimeter: 8*8 = 64 cm
What else can I help you with?
A regular octagon has an apothem measuring 10 in. and a perimeter of 66.3 in. What is the area of the octagon rounded to the nearest square inch?
To find the area of a regular octagon, you can use the formula: Area = (Perimeter × Apothem) / 2. Given the perimeter is 66.3 inches and the apothem is 10 inches, the area calculates to: Area = (66.3 × 10) / 2 = 331.5 square inches. Rounding to the nearest square inch, the area of the octagon is approximately 332 square inches.
A regular octagon with sides of length 7 and an apothem of length 10.49 has an area of?
Area in square units = 0.5*(apothem)*(perimeter)
What is the perimeter and the area of a regular octagon with 4 side and apothem a?
If the sides are of length 4 units then the perimeter is 8*4 = 32 units. Its area is then 77.255 square units.
Will a square and regular octagon tile?
Yes.
What regular figure can be used with a regular octagon to tessellate the plane?
Square.

How do you turn a 9x9 square into a octagon?
To turn a 9x9 square into an octagon you can cut corners off the square. It will not be a regular octagon though.
Will a square and regular octagon tile?
Yes.
What regular figure can be used with a regular octagon to tessellate the plane?
Square.
What shapes is always a regular polygon square trangle pentagon octagon?
A square.
A regular octagon with sides of length 11 and an apothem of length 8.85 has an area of what?
An apothem of a regular polygon is a segment from its center to the midpoint of a side. You can use the apothem to find the area of a regular polygon using this formula: A = pa/2 where p is the perimeter of the figure and a is the apothem. For a regular octagon with side length 11, the perimeter p = 8(11) = 88. So the area would be A = 88(8.85)/2 = 389.4 square units.
What Two regular polygons will combine to tessellate?
square and octagon
Can a square and a regular octagon fill a flat suface?
No but lots of them can.
Can a regular octagon and a square tessellate?
You cannot use a regular octagon on it's own to make a tiling pattern without any gaps. However a regular Octagon and a square can be used together to make a tessellation. Many people think that regular octagons tesselate on their own because they do not appreciate the need for no gaps.
What polygon is always a regular polygon?
A square, pentagon, decagon, octagon are always regular polygons.
