Area of a triangle: 1/2×b×h

You have 4 triangles
2 with base of 8 and height of 2
2 with base of 8 and height of 8

Find area for each of these
A = 1/2 × 8 × 2 = 8
A = 1/2 × 8 × 8 = 32

Since you have 2 of each 
8 × 2 = 16
32 × 2 = 64

Total area:
A = 16 + 64
   = 80 in²

Find the area of an equilateral triangle with 12-inch altitudes
Nina [5.8K]

\textit{height of an equilateral triangle}\\\\ h=\cfrac{s\sqrt{3}}{2}~~ \begin{cases} s=\stackrel{side's}{length}\\[-0.5em] \hrulefill\\ h=12 \end{cases}\implies 12=\cfrac{s\sqrt{3}}{2}\implies 24=s\sqrt{3}\implies \cfrac{24}{\sqrt{3}}=s \\\\[-0.35em] ~\dotfill

\textit{area of an equilateral triangle}\\\\ A=\cfrac{s^2\sqrt{3}}{4}\qquad \qquad A=\cfrac{~~ \left( \frac{24}{\sqrt{3}} \right)^2 \sqrt{3}~~}{2}\implies A=\cfrac{~~ \frac{24^2}{3} \sqrt{3}~~}{2} \\\\\\ A=\cfrac{192\sqrt{3}}{2}\implies A=96\sqrt{3}\implies A\approx 166.28

12³.2².4⁴ / 4³.2.12²
Nuetrik [128]
Remember
\frac{xyz}{abc}=( \frac{x}{a} )( \frac{y}{b} )( \frac{z}{c} )
and
\frac{x^m}{x^n}=x^{m-n}

split them to have same bases
\frac{12^32^24^4}{4^32^112^2}=
( \frac{12^3}{12^2} )( \frac{4^4}{4^3} )( \frac{2^2}{2^1} )=
(12^1)(4^1)(2^1)=
(12)(4)(2)=
