The area of the parallelogram is given by:
A = b * h
Where,
b: base
h: height
Substituting values we have:
A = (16.5) * (6)
A = 99 feet ^ 2

Answer:
9 packages of chocolate bars
Step-by-step explanation:
Let he bought c packages of chocolate bars and t packages of toffee bars,
Since, he bought 1 fewer package of chocolate bars than toffee bars.
⇒ c = t - 1 -----(1)
Also, he handed out out
of the chocolate bars and
of the toffee bars,
If he handed out the same number of each kind of candy bar.
![\implies \frac{2}{3}\times c=\frac{3}{5}\times t](https://tex.z-dn.net/?f=%5Cimplies%20%5Cfrac%7B2%7D%7B3%7D%5Ctimes%20c%3D%5Cfrac%7B3%7D%7B5%7D%5Ctimes%20t)
( By cross multiplication )
( Division property of equality )
From equation (1),
![c=\frac{10}{9}c-1](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B10%7D%7B9%7Dc-1)
![1=\frac{10}{9}c-c](https://tex.z-dn.net/?f=1%3D%5Cfrac%7B10%7D%7B9%7Dc-c)
![1=\frac{10c-9c}{9}](https://tex.z-dn.net/?f=1%3D%5Cfrac%7B10c-9c%7D%7B9%7D)
![1=\frac{c}{9}](https://tex.z-dn.net/?f=1%3D%5Cfrac%7Bc%7D%7B9%7D)
![\implies c = 9](https://tex.z-dn.net/?f=%5Cimplies%20c%20%3D%209)
Hence, he bought 9 packages of chocolate bars.
Answer:
D
Step-by-step explanation:
To find the discriminant you do b^2-4(a)(c), which in this case gives you -28. If your discriminant is less than zero, you will have no real roots.
