Answer:

Given: Each side of an equilateral triangle is 30 cm.

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━⠀⠀⠀

\underline{\bf{\dag} \:\mathfrak{As\;we\;know\: that\: :}}

†Asweknowthat:

⠀⠀⠀⠀

\star\:\boxed{\sf{\pink{Area \: of \: equilateral \: \triangle = \dfrac{\sqrt{3}}{\:4} (a)^2 \ cm}}}⋆

Areaofequilateral△=

(a)

2

cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Here, a is each side of the equilateral triangle.

⠀⠀⠀⠀⠀⠀⠀

Therefore,

⠀⠀⠀⠀

\begin{gathered}:\implies\sf Area_{\:\triangle} = \dfrac{\sqrt{3}}{2} \times \Big(30 \Big)^2 \\\\\\:\implies\sf Area_{\:\triangle} = \dfrac{\sqrt{3}}{2} \times 30 \times 30 \\\\\\:\implies{\underline{\boxed{\frak{\purple{Area_{\:\triangle} = 225\sqrt{3}\:cm^2}}}}}\:\bigstar\end{gathered}

:⟹Area

⠀⠀⠀⠀⠀⠀⠀

\therefore\:{\underline{\sf{Hence, \ Area \ of \ equilateral \ \triangle \ is \ \bf{225 \sqrt{3} \ cm^2}.}}}∴

Hence, Area of equilateral △ is 225

★AdditionalInformation:

Equilateral triangle is a triangle in which all the three sides have equal length.

The sum of all three angles of an equilateral triangle is equal to 180°

Altitude of equilateral triangle = \sf\dfrac{\sqrt{3}a}{2}

a

Perimeter of equilateral triangle = Sum of all sides. (a + a + a)
