This triangle is equilateral, since all three its sides are congruent segments a = 4 cm.


The area of every equilateral triangle with the side length "a" is

    area = %281%2F2%29%2Aa%2A%28a%2A%28sqrt%283%29%2F2%29%29= a%5E2%2A%28sqrt%283%29%2F4%29  square units.


In this problem,  the area of the triangle is

    area = 4%5E2%2A%28sqrt%283%29%2F4%29 = 4%2Asqrt%283%29 = 6.9282 cm^2  (rounded).    ANSWER

Solved.
