    D

    Step-by-step explanation:

    A square has 4 equal sides, so than divide 84 by 4 sides and you get 21.

    Area of a square is A^2, so just take 21^2 = 441

    D. 441

    Step-by-step explanation:

    All sides of a square are equal. Due to this, the perimeter can be expressed as 4 times the side of the square. Let x be the side of a square.

    Then we have:

    4x = 84

    x = 21

    The area of a square is written as x^2, as x is both the length and the width.

    So your answer will be:

    (21) ^2 = 441
