In the accompanying diagram, parallelogram ABCD has

Taya2010 [7]

Answer:

The area of the paralellogram is 24 square units.

Step-by-step explanation:

Geometrically speaking, the area of the parallelogram has an equation equivalent to the area formula for a rectangle, that is:

$A = b\cdot h$ (1)

Where:

$A$ - Area.

$b$ - Base.

$h$ - Height.

The base and height of the parallelogram are, respectively:

Base

$b = 8-2$

$b = 6$

Height

$h = 5-1$

$h = 4$

Then, the area of the parallelogram is:

$A = (6)\cdot (4)$

$A = 24$

The area of the paralellogram is 24 square units.

Including a 6% sales tax, an inn charges $155.82 per night. Find the inn's nightly cost before tax is added.

Feliz [49]

we know the Inn is charging 155.82 and that's 100% plus 6%, namely 106% of an amout of say that is "x", being the 100%.

since we know that 155.82 is 106%, what is "x"?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} 155.82&106\\ x&100 \end{array}\implies \cfrac{155.82}{x}=\cfrac{106}{100}\implies \cfrac{155.82}{x}=\cfrac{53}{50} \\\\\\ 7791=53x\implies \cfrac{7791}{53}=x\implies 147=x$
