Answer 1

Explicación paso a paso:

$01. \\ lado \: (l) = 12 \\ \\ A = \frac{ {l}^{2} \sqrt{3} }{4} \\ A = \frac{ {12}^{2} \sqrt{3} }{4}\\ A = \frac{144 \sqrt{3} }{4} \\ \boxed {A = 36 \sqrt{3} }\: \: o \: \: \boxed{A = 66.35}$

$02. \\ lado \: (l) = 20 \\ \\ A = \frac{ {l}^{2} \sqrt{3} }{4} \\ A = \frac{ {20}^{2} \sqrt{3} }{4}\\ A = \frac{400 \sqrt{3} }{4} \\ \boxed {A = 100 \sqrt{3} }\: \: o \: \: \boxed{A = 173.2}$

$3. \\ base = 8 \\ altura = 3 \\ \\ A = \frac{base \times altura}{2} \\ A = \frac{8 \times 3}{2} \\ A = \frac{24}{2} \\ \boxed{ A = 12}$

$4. \\ base = 12 \\ altura = 4 \\ \\ A = \frac{base \times altura}{2} \\ A = \frac{12 \times 4}{2} \\ A = \frac{48}{2} \\ \boxed{ A = 24}$
