Question 364412
The perimeter of a square is twice the perimeter of an equilateral triangular lot. If one side of the square is 60 meters, find the length of a side of the triangle.

Let S = perimeter of a square
  S/4 = side of square 
    T = perimeter of an equilateral triangular lot
  T/3 = length of side of equilateral triangle

    S = 2T

If S/4 = 60

    S = 240
    T = S/2 = 120

  T/3 = 120/3 = 40

The length of the side of the triangle is 40 meters
