Question

Find the area of equilateral triangle with side a.

Answer 1

Answer:

$\frac{\sqrt{3} }{4} a^2$

Step-by-step explanation:

To find the area of an equilateral triangle, we can apply a formula.

$A=\frac{\sqrt{3} }{4} s^2$

$A= area\\s=side \: length$

The side length is given a.

Plug a in the formula as the side length.

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