An equilateral triangle and a square have the same perimeter of 12 inches. What is the ratio of the area of the triangle to the area of the square? Express your answer as a common fraction.
Area of square = (12/4)^2 = 3^2 = 9
Area of equilateral triangle = (1/2) * 4^2 * sin (60°) = 8 sqrt (3) / 2 = 4sqrt (3)
Ratio of areas = [ 4sqrt (3) ] / 9
i think its 4/3.
