    Answer:

    The answer is C, E and F .

    Step-by-step explanation:

    Given that the area of square is, Area = length×width. In a square, all sides are equal so you have to substitute (2x+4) into the formula :

    Let length be (2x+4) inches,

    Let width be (2x+4) inches,

    Area = (2x+4)(2x+4)

    = (2x+4)² (option C)

    = 4x² + 16x + 16 (option F)

    = 4(x² + 4x + 4) ( Factorize )

    = 4(x+2)² (option E)

    You can use the formula, (a+b)² = a² + 2ab + b² to evaluate quickly.
