Question

if if the side of an equilateral triangle is 8 cm then find its area

Answer 1

Area of equilateral triangle = $side^2 \frac{ \sqrt{3} }{4}$

===========================


Here,

Side = 8 

----------------


Area of this triangle = $(8)^2 \frac{ \sqrt{3} }{4}$

                                  = $64 \frac{ \sqrt{3} }{4}$
                    
                                  = 16 × √3

                                  = 16√3  cm²




i hope this will help you
