Not exactly, 'homework'

I had a question on a test asking the following:
Quote:If the area of a rectangle is 8x^2 - 18x + 9
And the width is 0.75cm. What is a possible measurement for length in cm.


How would you solve this? (I got the answer, but my process might have been incorrect, so I want to see how other people would do it)

You're in grade 10, so I assume this is what you need to do.

Set area equal to zero, and solve for x using the quadratic formula. You end up with two positive real roots, 0.75, and 1.5. Therefore, 1.5 is the length.
