Question

The area of a rectangular athletic field is represented by the expression 9y^2-64z^2 square meters. Write an algebraic expression to represent one possible set of dimensions (in the sense “length times width”) of the athletic field. Include correct units with your solution

Answer 1

I just need to see if I have done it right. So this is the answer I have.
9y^2-64z^2
(3y-8z)(3y+8z)
L=(3y+8z)
W=(3y-8z)

Answer 2

Yep, that works.

Answer 3

For extra fun. Try picking values for y and z and see if they make sense for a rectangle.
