The area of the triangular athelic field is represented by an expression 81y^2-16z^2 square meters. Write an algebraic expression to represent one possible set of dimensions (in the sense of length times width)of the athelic field; include correct units.
Intermediate Algebra -
81y^2-16z^2 = (9y+4z)(9y-4z) Sq. meters.
Length = 9y+4z.
Width = 9y-4z.
