This should be easy but I'm getting tripped up for some reason. If the area of an equilateral triangle is x square meters and the perimeter is x meters, then what is the length of one side of the triangle in meters? Thanks in advance

Side of the triangle= s

Area of the triangle= s^2sqrt(3)/4= x

Perimeter of the triangle= 3s= x

s^2sqrt(3)/4=3s

s^2sqrt(3)=12s

s^2sqrt(3)-12s=0

s(s*sqrt(3)-12)=0

s*sqrt(3)-12=0

s=12/sqrt(3) or 4sqrt(3) meters.
