    Are you doing this math Olympiad?To solve this problem, you need to use the Pythagorean theorem, I will solve it, whether you can understand it is your business, because it is a regular hexagon, so each angle is 120 degrees, first make two auxiliary lines (that is, connect ac and de) to divide the hexagonal abcdef into a rectangle acdf and two triangles. (triangle abc, triangle def), and then connect the two points be and ac at the point g, in the triangle the middle side is at equal angles, so the angle bac 30 degrees, because in a right triangle the side of the 30 degree angle is equal to half of the hypotenuse, so bg 8 2 4.

    Using the Pythagorean theorem, the square root of ga (8 2-4 2) and the square root of 48 is approximately equal to.

    Think of a regular hexagon as two isosceles trapezoids, then the area (16+8)*keep three decimal places).

    Sorry, I don't know how to enter the root number on the computer, I can only use the form of decimals

    A square wax ruler is a quadrilateral with all four sides equal and all four corners at right angles. The two pairs of opposite sides of the square are parallel, the four sides are equal, the four corners are all right angles, the diagonals are perpendicular, bisected and equal to each other, and each diagonal is divided into a group of diagonals. A group of rectangles with equal adjacent sides is called a square, and a diamond with a right angle is called a square.

    The area of a square is the square of the length of the sides. The side length is eight, and the square of the height of the eight is sixty-four, so the area of this square is sixty-four.

    Regular octagon calculation method from the midpoint to each vertex line to obtain 8 isosceles triangles, after finding the area of the triangle and then multiplying it by 8, and knowing that the longest diagonal is 8, then the waist length of the isosceles triangle is 4, and the area of the triangle is calculated by the sinusoidal theorem. 1 2*4*4*sin(360 8)=8*sin45=4 times 2, so the area of the regular octagon is 8*4 times 2=32 times 2. Calculation of area Suppose any vertex of the regular octagon is p, and then count two squares to the left or right, let that point be q, and draw a line from p to q, if the length of this line is a, then the area of the regular octagon is.

    Summary. The formula for calculating the area of a regular octagon: s=8*a 2*tan( 8) where a is the side length of the regular octagon and is the pi, and tan( 8) is the tangent of the inner corner fan of the regular octagon.

    Therefore, if the side length is meters, then the area of the regular octagon is: s=8*m2

    I'm sorry I don't understand, but can you elaborate on that?

    The formula for calculating the area of a regular octagon: s=8*a 2*tan( 8) where a is the side length of the regular octagon and is the pi, and tan(8) is the tangent of the split inner corner fan of the regular octagon. Therefore, if the side length is the number of meters, then the area of the potato octagon is:

    s=8*m2

    Hello, it is a pleasure to serve you and give you the following answer: the area of the regular octagon is equal to the length of the meter side, and the area of the regular octagon is about the square meter of flat grinding. This problem occurs because the area of a regular octagon is more complex, requiring the calculation of the length of its eight sides, as well as the plane angle of each side.

    The solution to this problem is:1First, determine the side length of the regular octagon, such as meters; 2.

    Then, the plane angle of each row is calculated, that is, the angle between each edge and the horizontal line, and the angle of each edge is assumed to be 45°. 3.Finally, the length of each side and the value of each angle are substituted into the formula, that is, s=a*a*cos(45°)*4, where s is the area of the regular octagon and a is the length of the side, and the area of the regular octagon is calculated to be about square meters.
