The sides of a triangle are in arithmetic progression and its area is 3/5th the area of an equilateral triangle with the same perimeter.

Find the ratio of the sides of the triangle.

(In reply to Solution by Rachel Mantis)

You said, "...the area is √(3x/2)(x/2 + d)(x/2)(x/2 - d). Simplifying, this is x/2 * √3x^2/4 - d^2."

Check your math. It actually simplifies to x/2 * √(3x²/4 - 3d².
