Answer 2

`9x^2 - 30x + 25`

Explanation:

To solve for area, multiply the width times the height. In this case, since the shape is a square, the width is the same as the height. So, multiplying 3x - 5 times 3x - 5 should give us the area.

`(3x-5)(3x-5)\\(3x)(3x) + (3x)(-5) + (-5)(3x) + (-5)(-5)\\9x^2 - 15x - 15x + 25\\9x^2 - 30x + 25`

If you don't understand the algebra there, use an area model, and please let me know if you're not sure how to do that. I'll help you out as much as I can! :)
