well you will need the height and the base length of the triangle

yay i do some good

freckles · Answer

you are given the base length since you know you have an equilateral triangle and you are given one leg length 
since it is a equilateral triangle all legs of the triangle are equal 
now the height is just what you need 
and you will be ready to plug in
