If you double the perimeter of an equilateral triangle, you must, perforce, double the length of each of the sides. Since the area of an equilateral triangle is given by a numerical constant multiplied times the square of the measure of one of the sides, if you double the measure of a side, you must increase the area by the square of 2, i.e. 4.
