  1. Given:-

    • Area of the Equilateral Triangle = 36√3cm²

    To Find:-

    • Height of an equilateral triangle.

    Formula Used:-

    • [tex]{\boxed{\bf{Area\:of\: Equilateral\: Triangle=\dfrac{\sqrt{3}}{4}a^2}}}[/tex]
    • [tex]{\boxed{\bf{Height\:of\: Equilateral\:Triangle=\dfrac{\sqrt{3}}{2}a}}}[/tex]

    Solution:-

    Firstly,

    [tex]\sf :\implies\:Area=\dfrac{\sqrt{3}}{4}a^2[/tex]

    [tex]\sf :\implies\:36\sqrt{3}=\dfrac{\sqrt{3}}{4}a^2[/tex]

    [tex]\sf :\implies\:a^2=36\times4[/tex]

    [tex]\sf :\implies\:a^2=144[/tex]

    [tex]\sf :\implies\:a=\sqrt{144}[/tex]

    [tex]\bf :\implies\:a=12\:cm[/tex]

    Now,

    [tex]\sf :\implies\: Height=\dfrac{\sqrt{3}}{2}a[/tex]

    [tex]\sf :\implies\: Height=\dfrac{\sqrt{3}}{2}\times12[/tex]

    [tex]\bf :\implies\: Height=6\sqrt{3}\:cm[/tex]

    Hence, The Height of the Equilateral triangle is 6√3 cm.
