Question

Find the area of an equilateral triangle whose each side is $a$ cm.

Answer 1

Find the area of an equilateral triangle:

It is known that the area of the equilateral triangle can be given as: $\frac{\sqrt{3}}{4}{\left(side\right)}^2$

Hence the area for, $side=acm$ will be,

$area=\frac{\sqrt{3}}{4}{\left(a\right)}^2$

Hence, the area of the equilateral triangle is $\frac{\sqrt{3}}{4}{a}^{2}c{m}^2$.
