The area of a rectangular athletic field is represented by the expression 81y^216z^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.

all you need is a set of factors of the expression
how about
81y^2  16z^2 = (9y+4z)(9y4z)
make one the length, the other the width.
