    because the area of a rectangle is length times width.

    So 4x16=64

    Now we know that a square's area is one of the sides multiplied by itself.

    So we could say its y//2.

    If we set these up to each other since the area of the rectangle is equal to the area of the square. it would look something like this.

    64=y//2

    If we take the square root of both side we would get y=8.

    So one side of the square, y, is a total length of 8.
