Step-by-s:

EL PERÍMETRO DE UN TRIÁNGULO ES LA SUMA DE SUS LADOS Y EL

TRIÁNGULO EQUILÁTERO TIENE SUS 3 LADOS IGUALES Y DE ESTO

SE ENCUENTRA LA LONGITUD DE CADA UNO DE SUS LADOS.

L = 60 cm/3 = 20 cm

AHORA SE CONSIDERA COMO SI FUERA UN TRIÁNGULO RECTÁNGULO.

DESPUÉS SE DESPEJA EL TEOREMA DE PITÁGORAS PARA ENCONTRAR

LA ALTURA.

<em>h</em> = \sqrt{(20 cm)^{2} - (10 cm)^{2}} = 17.32 cm^{2}

LUEGO SACAMOS EL ÁREA DEL TRIÁNGULO EQUILÁTERO COMPLETO.

<em>A</em> = 20 cm(20 cm)/2 = 200 cm^{2}

Answer:

173.21cm^2

Step-by-step explanation:

A=\frac{\sqrt{3} }{4} a^2\\P=3a\\

Solve for A

A=\sqrt{3} \frac{P^2}{36} \\=\sqrt{3} *\frac{60^2}{36} \\=173.21cm^2
