    Answer:

    a. 3x = 45

    15cm

    Step-by-step explanation:

    Given the perimeter of an equilateral triangle = 45cm .

    Using the equation

    3x = 45

    Divide both sides by 3

    x = 45/3

    = 15cm

    The length of each side of the triangle is 15cm because an equilateral triangle has its three sides equal
