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?

A 6

B 8

C 4√2

D 2√3

E 4√3

Let the side of triangle be a meter

Area of equilateral triangle = x square meters = √3*a^2/4

perimeter = x meters = 3a

x/x = (√3*a^2/4)/3a

(√3*a)/(3*4) = 1

a = 4√3

Answer E
