Answer:
Perimeter_hexagon
= 78 inches
Step-by-step explanation:
"Regular hexagon" means the shape has 6 sides and all the sides are the SAME length.
"equilateral triangles" means the triangles all three sides are the same.
"perimeter" is distance around the outside of a shape.
see image.
So if the triangle has perimeter 39 inches. We divide to find the length of a side.
39/3
= 13.
The side of the triangle is also the side of the hexagon.
Perimeter of the hexagon is
P = 6•side
P = 6•13
P = 78
see image.
