    Lengths of the sides = 7 cm.

    Step-by-step explanation:

    An equilateral triangle is a triangle in which all three sides are equal.

    If the side length of the equilateral triangle = x

    The perimeter of the equilateral triangle = 3x

    Given:

    A garden is in the shape of an equilateral triangle and its perimeter = 21 cm

    So, each side length of the garden = 21/3 = 7 cm.
