The area of a rectangular athletic field is represented by the expression 16y²49z² 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.

Area = 16y²49z² = (4y)²(7z)²
Factorize to get
(4y+7z)(4y7z).
Can you take it from here?
