The area of a rectangular athletic field is represented by the expression
36y^2-81z^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
---------------------
36y^2-81z^2
Factor:
(6y-9z)(6y+9z)
---
Let width be 6y-9z
Let length be 6y+9z
