The area of the quadrilateral shown is 252 square inches. what is the perimeter? (the width is 16.8 inches) a. 61.8 inches b. 31.8 inches c. 63.6 inches d. 67.2 inches

The answer is 63.6

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= 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:

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

For this case we have the following function:

c = f (b) = 10b

Where,

b: number of boxes

c = f (b): total cost

The domain of the function is:

b ∈ [0, ∞)

Where, the numbers belonging to the domain are whole numbers.

Therefore, the domain of the function are all natural numbers

The domain of the function is:

b ∈ ℕ
