    4.2 inches

    Step-by-step explanation:

    The formula to find the area of a rectangle is A=2L+2W

    When you plug in the information you already have, the equation is now 42=2 (16.8) + 2W.

    Multiply 2 and 16.8 to get 42=33.6+2W

    Subtract 33.6 from 42 and you get 8.4=2W

    Divide both sides by 2 and you get 4.2=W

    2.5 inches

    Step-by-step explanation:

    The area is given by the formula ...

    A = LW

    Putting in the given numbers for length (L) and area (A), we can find width (W).

    42 in^2 = (16.8 in) W

    42 in^2 / (16.8 in) = W = 2.5 in

    The width of the rectangle is 2.5 inches.
