Answer:

  30 ft

Step-by-step explanation:

The perimeter of the square is 4 times the side length:

  4 × 45 ft = 180 ft

If that is twice the length of the perimeter of the triangle, then the triangle's perimeter is (180 ft)/2 = 90 ft

The perimeter of an equilateral triangle is 3 times the side length, so each side of the triangle is ...

  (90 ft)/3 = 30 ft . . . triangle side length
