Find the area of an equilateral triangle with radius 8sqrt3 m.

Question

Leave your answer in simplest radical form.

Answer 1

Radius,r=8√3 m

Height of triangle ,h=2r

                                   =16√3 m

Side of the triangle ,a=16√3/sin60

                                       =32 m

 

Area of the triangle,A=√3/4(a^2)

                                     =√3/4(32^2)

                                     =443.4 m^2
