Question

Area of equilateral triangle is 9 root 3 find its altitude

Answer 1

Answer:

ans is 31.2

Step-by-step explanation:

let a be the side of the triangle,

as we know that area of eq. triangle = sqrt3/4a

                           >> 9sqrt(3)=sqrt(3)/4a

                         >> a=36

 hence drop perpendicular to its base which divides base into two and apply pythagoras theorem to find its altitude .
