Let's separate this shape into three parts. A smaller rectangle at the top, and one at the bottom, and a bigger rectangle in the middle.
The smaller rectangle at the top:
The equation to find the area of a rectangle is
(a = area, l = lenght, w = width)
a = l · w
Put in the values
a = 18 · 3
a = 54
Since the smaller rectangle at the bottom has the same length and width, it has the same area.
The bigger rectangle in the middle:
a = l · w
Put in the values
a = 8 · 9
a = 72
Now add all of the areas together to get the answer!
72 + 54 + 54 = 180
The answer is 180 :)

Answer:
<h2>204 units²</h2>
Step-by-step explanation:
It's a rectangle. Therefore the opposite sides are congruent.
We have the equation:
2x + 4 = 12 <em>subtract 4 from both sides</em>
2x = 8 <em>divide both sides by 2</em>
x = 4
Put the value of x to the expression 4x + 1:
4(4) + 1 = 16 + 1 = 17
Therefore we have the rectangle with dimesions 17 × 12.
The area of the rectangle:
A = (17)(12) = 204
Answer:
$37.
Step-by-step explanation:
Firstly, let's set the price of each pair of shoe to be x.
Since each pair of shoes costs the same, and there are three pairs, we can set the original price to be 3x.
Now, to apply the shipping charge, all we have to do is add 7.50 to 3x, getting 3x + 7.5.
Next, to apply a 6% tax, we can multiple the whole expression by (100% + 6%), getting (3x + 7.5) 
106%.
Since the whole bill foots to a total of $126.81, we can set the final equation to be:
