I need help with a Math question.....Area of a square....

how do you solve: "find the area of a square with sides (3x)/(4x^2-9x)?" Thank you for your help.

s^2 = A

[3x / (4x^2 - 9x)]^2 = A

9x^2 / (16x^4 - 36x^3 - 36x^3 + 81x^2)

9x^2 / (16x^4 - 72x^3 + 81x^2)

9x^2 / x^2(16x^2 - 72x + 81)

9 / (16x^2 - 72x + 81) = A

-
(3x)^2/(4x^2-9x)^2
9/(4x-9)^2
