19.98 = x + x(1.6)
19.98 = 1.6x + x
19.98 = 2.6x
x = 7.68
x(1.6) = 12.29
The cost is $7.68 and the markup is $12.29. (Approximate due to rounding)
Hope this helps!! :)
A. 61.8 inches
B. 31.8 inches
C. 63.6 inches
D. 67.2 inches
Answer:
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
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
