Answer:
36[tex]\sqrt{3}[/tex] square units.
Step-by-step explanation:
The triangle shown is an equilateral triangle. This means all the side lengths are 12. The formula for the area of an equilateral triangle is [tex]a^{2}[/tex]([tex]\frac{\sqrt{3} }{4}[/tex]).
Plug in 12 for a.
144[tex]\sqrt{3}[/tex]/4
= 36[tex]\sqrt{3}[/tex]
