What is the area of a trapezoid ABCD with bases AB and CD ,
Mrrafil [7]

check the picture below on the top side.


we know that x = 4 = b, therefore,  using the 30-60-90 rule, h = 4√3, and DC = 4+8+4 = 16.


\bf \textit{area of a trapezoid}\\\\&#10;A=\cfrac{h(a+b)}{2}~~&#10;\begin{cases}&#10;a,b=\stackrel{bases}{parallel~sides}\\&#10;h=height\\[-0.5em]&#10;\hrulefill\\&#10;a=8\\&#10;b=\stackrel{DC}{16}\\&#10;h=4\sqrt{3}&#10;\end{cases}\implies A=\cfrac{4\sqrt{3}(8+16)}{2}&#10;\\\\\\&#10;A=2\sqrt{3}(24)\implies \boxed{A=48\sqrt{3}}


now, check the picture below on the bottom side.


since we know x = 9, then b = 9, therefore DC = 9+6+9 = 24, and h = b = 9.


\bf \textit{area of a trapezoid}\\\\&#10;A=\cfrac{h(a+b)}{2}~~&#10;\begin{cases}&#10;a,b=\stackrel{bases}{parallel~sides}\\&#10;h=height\\[-0.5em]&#10;\hrulefill\\&#10;a=6\\&#10;b=\stackrel{DC}{24}\\&#10;h=9&#10;\end{cases}\implies A=\cfrac{9(6+24)}{2}&#10;\\\\\\&#10;A=\cfrac{9(30)}{2}\implies \boxed{A=135}

Find volume of a A hexagonal prism
klasskru [66]
The prism volume is given by:
 V = (6) * (1/2) * (L) * (ap) * (h)&#10; 
 Where,
 L: hexagon side
 ap: hexagon apothema
 h: prism height
 Substituting values we have:
 V = (6) * (1/2) * (11) * (9.5) * (7)&#10;&#10; V = 2194.5 feet ^ 3
 Answer:
 
The volume of the hexagonal prism is given by:
 
V = 2194.5 feet ^ 3
