Question 1091227
What is the side length of an equilateral triangle whose area is radical 3 cm squared?
-----------
Area of an equilateral triangle with side lenght s:
Area = b*h/2
{{{Area = s*sqrt(s^2 - (s/2)^2)}}}
{{{Area = s*sqrt(s^2 - s^2/4)}}}
{{{Area = s*sqrt(3s^2/4)}}}
{{{Area = s*(s/2)sqrt(3)}}}
--------------------------
Do you see the answer?
=========================
PS  Don't use "radical 3"
Use sqrt(3)
