    X=7

    Step-by-step explanation:

    Since area of a rectangle is 294

    Area of a rectangle=length*breadth

    Let's the width be x

    Since length is 6 times of width=6x

    Area=l*w

    294=x*6x

    294=6x^2

    Divide both sides by 6

    x^2=49

    Square root both sides

    x=7

    Therefore x is 7
