I found the image that should have accompanied this problem.
Given:
equilateral triangle with sides that measures 7cm.
hexagonal shape meaning 6 sides or 6 equilateral triangles used.
Area of an equilateral triangle = √3/4 * a²
A = √3 /4 * (7cm)²
A = 1.73/4 * 49cm²
A = 21.20 cm²
21.20 cm² * 6 tiles = 127.20 cm² ARea of the hexagon.
