Question

the perimeter of hexagon is 14 cm how long it's side is​

Answer 1

We have given regular hexagon. If we join each side into center then we get 6 equilateral triangle.

We know that area of equilateral triangle = √ 3/4a^2

a =14 , (given)

area of equilateral triangle = √3/4 (14 x14)

=> area of equilateral triangle = 1.732 x49

=> area of 6 equilateral triangle = 1.732 x49 x 6

=> area of 6 equilateral triangle = 509.208 sq cm
