What is the area of a regular hexagon with sides 1 in. long?
Read Solution (Total 7)
-
- A regular hexagon of side 1 inch can be divided in to 6 equilateral triangle of side 1 inch.
Area of each triangle = (root 3/4)* side^2 = (root 3/4)
Area of 6 triangles = 6*(root 3/4)= 1.5 root 3= 2.59 square inch - 13 years agoHelpfull: Yes(7) No(0)
- Area of hexagon= [3*3^(1/2)*t^2], where t is lem=ngth of each side.
Therefore the area of 1 in. lenght is=2.59 in.^2 - 13 years agoHelpfull: Yes(2) No(1)
- area of regular polygonal =(n*a^2/4)*cot(180/n)
n= no of sides
a=length of side
6*1^2/4(cot(180/6))
6/4*cot(30) cot(30)=1.717
(6*1.717)/4

- Regular Hexagon has 6 equilateral triangle.
In general Area of Triangle = (bh)/2.
For equilateral triangle b=h. Therefore Area= b^2/2.
1 Hexagon = 6 equilateral Triangle
Area of Hexagon = 6(b^2/2)= 3(b^2)
b=1, so Area of hexagon is 3 sq units.

- its a regular hexagon.....so,,if we divide it we get two trapeziums.....
area of trapezium=h(each side+length of largest diagonal)/2
now we get the angle divided as 60 degree each....
the length of "h"=1*sin(60)=root(3)/2
and the base will be=1*sin(30)=1/2
the other side will also be 1/2
the length of the diagonal will be=2 inch..
now from the formula=(root(3)*3/4)*2 (because we have two trapeziums)
ans will be :3root(3)/2 - 12 years agoHelpfull: Yes(0) No(0)
- (3*3^.5)/2
its formula - 12 years agoHelpfull: Yes(0) No(1)
- a regular hexagon can be considered as 4 equilateral triangles + 2 squares each have side 1 inch
s0 area=4*(root3)/4*a*a+2*a*a where(a=1)
so area=2+(root3)=3.732 in^2 - 11 years agoHelpfull: Yes(0) No(0)
