What is the area, in square centimeters, of the shaded part of the rectangle below?

vovangra [49]

Answer:

probably it

Step-by-step explanation:

First, get the area of the rectangle then subtract the triangle, the result will be the shaded area:

area rec = 18 * 11

area rec = 198 cm²

small side of tri = 11 - 5

small side of tri = 6 cm

area tri = (height * width) / 2

area tri = (6 * 18) / 2

area tri = 108 / 2

area tri = 54 cm²

area shaded = 198 - 54

area shaded = 144 cm²

12 pack for $3.50

vlada-n [284]

The savings per unit between the best deal and worst deal is about $0.06

$\texttt{ }$

<h3>Further explanation</h3>

Let's learn about the basic formula about Profit and Loss

$\texttt{Profit = Selling Price - Cost Price}$

$\texttt{Selling Price = Cost Price ( 100\% + Profit\% )}$

$\texttt{Loss = Cost Price - Selling Price}$

$\texttt{Selling Price = Cost Price ( 100\% - Loss\% )}$

<em>Let us tackle the problem !</em>

$\texttt{ }$

<em>12 pack for $3.50 → 144 pack for </em> $\$ 3.50 \times \frac{144}{12} = \$ 42$

<em>24 pack for $6.00 → 144 pack for </em> $\$ 6.00 \times \frac{144}{24} = \$ 36$

<em>36 pack for $8.50 → 144 pack for </em> $\$ 8.50 \times \frac{144}{36} = \$ 34$

<em>48 pack for $11.75 → 144 pack for </em> $\$ 11.75 \times \frac{144}{48} = \$ 35.25$

$\texttt{ }$

<em>From information above, we can conclude that:</em>

The Best Deal → 36 pack for $8.50

The Worst Deal → 12 pack for $3.50

$\texttt{ }$

<em>The savings per unit between the best deal and worst deal :</em>

$( \$ 3.50 \div 12 ) - ( \$ 8.50 \div 36 ) = \$ (\frac{1}{18}) \approx \boxed {\$ 0.06}$
