The area of a rectangular athletic field is represented by the expression 81y^2-16z^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.

Question

anonymous · Answer

this would probably be based on the difference of two squares, 
(9y+4z)(9y-4z) = 81y^2-16z
so the dimensions cab be of length (9y+4z) and width (9y-4z)
