Respuesta :
Length of the common side = 20/3 = 6 2/3 cm.
The perimeter of the hexagon = 6 * 6 2/3 = 6 * 20/3
= 120/3
=40 cm answer
The perimeter of the hexagon is 40 cm.
What is perimeter of equilateral triangle?
Perimeter of equilateral triangle is defined as addition the lengths of the equilateral triangle's three sides.
Perimeter of an equilateral triangle = 3A
Let each side of triangle = A
Since perimeter of an equilateral triangle = 3A
The perimeter of given triangle is 20 cm
So 3A = 20
A = 20/3
Thus, each side of triangle = 20/3
The perimeter of the hexagon = 6×side of triangle
The perimeter of the hexagon = 6×(20/3)
The perimeter of the hexagon = 2×20
The perimeter of the hexagon = 40 cm
