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 [tex]in^2[/tex]

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:

[tex]A=a*b[/tex]

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:

[tex]252=a*16.8\\a=\frac{252}{16.8}\\a=15[/tex]

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 [tex]in^2[/tex]
