Answer 1

Hi...☺️

Here is your answer...✌️
==================================

Given that ,
Side of equilateral triangle , a = 8cm

We know that,

Area of equilateral triangle

$= \frac{ \sqrt{3} }{4} {a}^{2} \\ \\ = \frac{ \sqrt{3} }{4} \times 8 \times 8 \\ \\ = \sqrt{3 } \times 2 \times 8 \\ \\ = 16 \sqrt{3} \: {cm}^{2}$

Answer 2

area of equilateral triangle = root 3/4* (8)^2
area = 27.71cm sq.
