    Answer:

    Area of equilateral triangle = 81√3 cm²

    Step-by-step explanation:

    Given:

    Perimeter of an equilateral triangle = 54 cm

    Find:

    Area of equilateral triangle

    Computation:

    Perimeter of an equilateral triangle = 3 x Side

    54 = 3 x Side

    Side of equilateral triangle = 54 / 3

    Side of equilateral triangle = 18 cm

    Area of equilateral triangle = [√3/4]side²

    Area of equilateral triangle = [√3/4][18]²

    Area of equilateral triangle = [√3/4][324]

    Area of equilateral triangle = [√3][81]

    Area of equilateral triangle = 81√3 cm²
