A regular hexagon has sides 2 feet long. What is the exact area of the hexagon? What is the approximate area of the hexagon?
nexus9112 [7]

The formula for the area of a hexagon is

A=\frac{3\sqrt[]{3}}{2}s^2

where 's' is the length of one side of the regular hexagon.

The side of our regular hexagon is 2 feet, therefore, its area is

\begin{gathered} A=\frac{3\sqrt[]{3}}{2}\cdot(2)^2=6\sqrt[]{3} \\ 6\sqrt[]{3}=10.3923048454\ldots\approx10 \end{gathered}

The exact area of the hexagon is 6√3 ft², which is approximately 10 ft².

How do you start this and find the weight of each shape? I do not remember doing this in class.
suter [353]
Let's say   make the shapes, some variable name

say   

⛁    ⚪     ◽    ▯
a     b      c     d

so.. if take those are the shapes provided

then we can take a look at the first set and we can say that

2a + b + c = 20

a + 4d + b = 19

a + c = 9

3c + d + a = 19 

thus     \bf \begin{cases}
2a + b + c = 20\\
a + 4d + b = 19\\
a + c = 9\\
3c + d + a = 19 
\end{cases}\\\\
-----------------------------\\\\
a+c=9\implies \boxed{c}=9-a\qquad thus
\\\\\\
2a+b+\boxed{9-a}=20\implies \underline{b}=11-a\impliedby thus
\\\\\\
a+4d+\underline{11-a}=19\implies d=\cfrac{8}{4}\implies d=2\\\\
-----------------------------\\\\
then\qquad 3\left(\boxed{9-a } \right)+\boxed{2}+a=19\implies 27-3a+2+a=19
\\\\\\
10=2a\implies 5=a

and surely you can find the other two
