    C. 63.6 inches

    That is because to find the length of the quadrilateral do this since you already know the width of the polygon:

    252/16.8 = 15

    Now that we know the length do this since this is the formula to find the perimeter or for me I would just 2x:

    2(16.8) + 2(15) =

    33.6 + 30 = 63.6

    The perimeter of the quadrilateral is 63.6 inches

    Answer:

    The answer is 63.6 in^2

    Step-by-step explanation:

    In order to determine the area of the quadrilateral, we have to know the values of its sides. The area of the quadrilateral is:

    A=a*b

    a= length of the quadrilateral

    b=width of the quadrilateral

    We know the area and the width of the quadrilateral, so we can determine its length:

    252=a*16.8\\a=\frac{252}{16.8}\\a=15

    Then, the perimeter of the quadrilateral is:

    P=2*a+2*b

    P=2*15+2*16.8

    P=63.6

    Finally, the perimeter is 63.6 in^2
